U are a world class teacher sir. You always say what we want to hear without going into other unrelated stuff like most teachers do. In short, U get straight to the point. I like that. Thanks for the tuts.
Thanks! Actually, lightning can strike the same spot twice. There's a place near my grandmother's house that has been struck at least six times. Tall structures such as building and bridges can get struck multiple times during a single storm. The idea that it won't strike the same place twice is simply a myth.
This is one awesome illustration. Came to youtube just for the answer about how lightning is formed and now taking away a great idea. Thank you! Was also thinking...if caught under an open field for whatever reason, would someone running towards safety- would they still carry those charged protons? how would the charges behave? (Extra questions I have for anyone who also might've been as curious as me, open to theories too just as food for thought) -would our geographic elevation play a role, or the density(heavyness of clouds) relative to the ground? like getting away from that area -would it be better to keep shoes on? wear crocs? be barefoot? -is there an ideal material to step on? -would it better to sit down, hold on to someone? I live in Florida 😅🙏🏽 I'm starting to count my blessings with the unpredictable spontaneity of our forecasts.
I can make lightning. You put the 4 elements together. 1. Earth (to hold the water) 2. Water 3. Fire (to produce a moist updraft) 4. Wind You got to find a valley where the air is dense and has a creek running through it. Some dead trees available. You got to dig a deep hole and contain it with Earth or clay. Then you wait until clouds come. A day before rain is expected you release a heap of hot updraft and the water helps make a moist updraft. Then when the cold cloud approaches they mix. It's best when the barometer says low. It's the 5th element. 1,500 to 2,000°C or above. You got to raise the wood off the ground to put more oxygen to it. Burn for at least 6 hours. It's the air temperature and moisture levels that play the biggest part. Because spring has come I reduced my fuel load to 50% less but hail fell and a big storm came. Then someone came onto my land and destroyed my firepit. So it's an indication that I'm onto it and someone is trying to delay my progress. It's science and physics. Water takes a lot of energy to heat up so you need to balance the ratio
The electron in the cloud are being attracted to the protons in the ground, so the electrons are pushing at the edge of the cloud to get to those protons
Sunny Apples if you look at National Geographic‘ slight big video, it is explained that the weight of charges are separated during a storm, and that’s why lightning doesn’t always appear to strike the ground. It can be generated within the cloud itself.
@JonathanAnonymous I think (although I'm not sure, and also realize that lightning is not perfectly understood and people debate about this) that the polarization in the cloud could be either way. So the bottom of the cloud could be positive, in which case it would attract electrons from the ground.
i've heard some claims that lightening can jump from the earth to the clouds as well, my guess would be "yes", if the charges are in the desired polarity and the distance is within range for a bolt to generate. This also answers the question of why raincoats are plastic and/or rubbery
The video was wonderful and easy to understand.I have a doubt how positive and negative charges are formed on the clouds? and The clouds Instead of inducing charges on the air nearby it is inducing charges on the ground first howcome air is not induced first and ground is induced first?
Yes, I think that is correct. Charge jumping from one plate to another is essentially a tiny bolt of lightning. This would occur at low voltage when the plates almost touch, but not quite. Note that in a capacitor this is typically not the desired result.
Damage from electrical transients or surges, is one of the leading causes of electrical/electronics equipment failure. An electrical transient is a short duration, high-energy impulse that is imparted on the normal electrical power system whenever there is a sudden change in the electrical circuit. They can originate from a variety of sources, both internal and external to a facility. Power surges are short duration voltage and current impulses that occur continuously in electrical distribution systems. Lightning, utility activities such as load or capacity bank switching and surges from motor drivers are all examples of power surges. The most obvious source is from lightning, but surges can also come from normal utility switching operations, or unintentional grounding of electrical conductors (such as when an overhead power line falls to the ground). Surges may even come from within a building or facility from such things as air conditioners, elevators, motors/pumps or arc welders, to name a few. In each case, the normal electric circuit is suddenly exposed to a large dose of energy that can adversely affect the equipment being supplied power. A surge protection device (SPD) is designed to divert high-current surges to ground and bypass your equipment, thereby limiting the voltage that is impressed on the equipment. The best means of protecting your electrical equipment from high-energy electrical surges is to install SPDs strategically throughout your facility. Considering that surges can originate from both internal and external sources, SPDs should be installed to provide maximum protection regardless of the source location. For this reason, a "Zone of Protection" approach is generally employed. The first level of defense is achieved by installing an SPD on the main service entrance equipment (i.e., where the utility power comes into the facility). This will provide protection against high energy surges coming in from the outside, such as lightning or utility transients. However, the SPD installed at the service entrance will not protect against internally generated surges. In addition, not all of the energy from outside surges is dissipated to ground by the service entrance device. For this reason, SPD’s should be installed on all distribution panels within a facility that supply power to critical equipment. Similarly, a third zone of protection would be achieved by installing SPD’s locally for each piece of equipment being protected, such as PLC’s, computers or computer controlled devices. Each zone of protection adds to the overall protection of the facility as each helps to further reduce the voltage exposed to the protected equipment. The service entrance SPD provides the first line of defense against electrical transients for a facility by diverting high-energy, outside surges to ground. It also lowers the energy level of the surge entering the facility to a level that can be handled by downstream devices closer to the load. Electrical transients are not confined to the electrical distribution system. They can enter a facility through phone/fax lines, cable or satellite systems, and local area networks (LAN). Therefore, in order to achieve maximum protection from surge damage, SPD’s should be installed on all systems susceptible to electrical transients. For maximum protection, SPD’s should be installed as close to the equipment (depends upon the type of arresters) being protected as possible. Cable lengths should be as short and straight as possible to minimize the resistive path of the circuit to ground. A solid connection to the system grounding conductor is essential for proper operation of the SPD’s. The surge protectors should be equipped with indicators that show if the circuit is grounded and operating properly, and the units installed so these indicators can be easily inspected.

The direction of the electric field is from the positive electrode to the negative electrode. So are you saying that the flow of the electrons is OPPOSING the force and direction of the electric field?
Good question. I read the friction theory in a NOAA publication, and also in a book on lightning (can't cite the source from memory, sorry). Friction is well know as a means to separate charges, but it does seem odd to imagine it occurring between water and ice particles. I don't know about *converting* all of the sunlight to UV, but catching the UV before it enters the atmosphere, such as with the solar panels on the space station, certainly produces power more efficiently.
This clip is mistaken on one point: Things that are pointy do not have a higher positive charge. The air is insulation and taller things have less insulation between themselves and the charge in the cloud making them the prime point to arc a discharge from the clouds.
I believe both ideas are correct. Being taller, trees provide an easier path to the ground, as you say. But also the charge does in fact concentrate at corners and points. Gauss was able to show this (Gauss's Law) and this particular idea is embodied in Maxwell's Equations, which are foundational to our understanding of electricity.
Heavy electrical forces motion collision are created only with limited matferials such as icluding magnets and good conductors, metals ... are clouds containers of such mattals? Eventhu n uclears blasts all of them on earth if explded do not create such heavy sound as simple thinder sound. Lighening occurs aftexr thunder. What was colluding? Electrical charges. Can you creat such charges making heAvy sound like thunder. Remember; thunder is not a result of Collison of matteris. It is not sound of Collison. Listen to it carefully-different sound than Collison.it is like the cloud is talking, no collision Right?Thanks.
What about next explaining what causes the positive molecules to concentrate up the clouds and the positive down the ground... The. What happens when the lightening gives the first spark...
My own guess is that a thick rubber shoe might not offer much protection. I think it also might be different if you were on a flat surface, such as concrete, or on grass, where the grass might reach up and make substantial contact above the rubber sole. I'm just guessing, though. Not something you want to experiment with!
nice drawing I do science at my school we were learning about that how about the water if you are in water will the lighting hit the water either way is it true that if you are close to the grown just your feet on the floor you will like survive maybe how are you safe in the car I thier are windows can the lighting hit the windows ?
The attraction on the cloud, applies to the surface of the car as well, shouldn't it have some charge as well, or polarize maybe? Good video btw, thank you !
@1990Shaolin Yes, and that's a good question. A person lying on the ground would not tend to have charge concentrating on them as strongly as a person standing up in a more "pointy" orientation. As far as I understand it, that should be a safer position.
where do they get from in the cloud, these free charges? do you mean that cloud by induction tear off electrons from their molecules (on the ground, trees, water) ?
Hey 👋 I got a question for you that I am unable to find an answer to myself . My question is, “Cam fireworks and composition of chemicals in them cause Storm/Rain (change weather in general) ?” . I think it’s possible because of the metals used in them for creating colours and thus the electron exchange between those particles and negatively charged atmosphere .
That's actually really hard as they contain really less amount of metals for the coloring and that amount can't handle the huge charge . And I'm not sure metal's are the only things that can be used there Non metals might be useful too🤨
In a lightning Storm the most suggested option is to not stand up, stay laiying or seated down and far away from metalic or electro conductinle materials..,
Does anybody know anytin4 about an irrational fear of litenin?..i`ve met sveral intellicent adults(usually female) sufferin from wot seems like a ysterical and paralyzin fear of tunder n litenin,despite knowin and understandin science involved .
It’s because the electrons (the negative charge) is attracted to the ground, which is why all f the electrons are pushing down at the edge of the cloud. The protons (positive charge) don’t move, but are just spread evenly throughout the cloud
Yes! Because somehow the earth can be both positive and negative charged and not short circuit itself! I think that it's very clear that something is wrong with this explanation.. it doesn't work.
when Ice crystals hit each Other and make negative charges at bottom and positive charges at top of cloud why they don't attract to each other in the same cloud to become neutral ??
Hai thanks for ur video. i still have one doubt. how tree and house getting charged though they are insulators? why not electrons on top of the car moves away and make it positively charged by induction?
Thunder and lighening in the clouds dispurse water and icegiving them degind shape. I.e small balls of ice and thiner lines of water. Right? So, clouds and rain have no relation with evaporated earth waters. Right?
Defined shape, very highly defined shape and dimension of snow and rain water , predefined sapes of snow and rain water comes from the creator sources, intelligent works, not from charges. Right?Thanks.
Whats the best way to attract lightning cheaply because I would like to observe it up close while in my car with some quick setup like maybe a iron bird bath with a couple of star shaped helium balloons tied to it. The string would of course be long so as to make it the tallest object out their and I would deploy it in a open field to increase the chances of a strike. I know I do this at my own risk so what do you think? The bird bath would have a stand rather then being hammered into the ground
The answer to that is pretty complicated. If I remember correctly, the concentration at the points follows as a result of Gauss' Law, and that requires at least a couple of semester of calculus to prove. I don't know of a simpler, more intuitive explanation, but I'll give it some thought.
This illustration isn't 100% accurate is it? Doesn't ground strikes usually come from both the clouds and ground (positive streamers), meeting somewhere in the air?
If I understand it correctly, it can go either from cloud to ground or from ground to cloud, and a typical bolt of lightning will involve several strokes back and forth. I don't think it would meet in the middle, though. Also, however, it is my understanding that this is something that is not completely understood and is an area of active discussion and debate among scientists and meteorologists.
No it is very inaccurate one tires don’t insulate a cars or trucks metal is in tires it not just rubber, and a vehicle can be struck. Also lighting does not go one way you have neg downward leader and a positive leader pos goes up neg goes down. And they meet the light you see travels up.
Thank you so much for the video! :D Question: Is that the same effect when the two plates of a variable parallel plate capacitor touch? Because one is negatively charged and the other one is positively charged. I observed at the lab that when the two plates touched at a potential of 30 volts approximately I could see little purple ''lightning bolts''. Is that analogous to a negatively charged cloud and positively charged object on the ground as you mentioned in the video?
Now we will talk about lightning. You see done clouds here. What you are seeing is just the bottom edge of the clouds. Thunder clouds can really be very tall-several miles high in many cases and weather inside the clouds the movement varies up and down can cause movement of charge inside the clouds and you can get a buildup of charge positive charge for example at the top of the charge and negative charge at the bottom. So I'll draw some negative charge here representing a bunch of negative charges building up at the bottom edge of these clouds. And again this is happening menopause weather inside the cloud moving inside the cloud. The cloud is basically broke polarized What you see here is You talk about charges but WHAT ARE charges?
As a general rule that is correct. The ground is the reference point and is considered zero voltage. This changes during an electrical storm, though. The charge on the cloud can cause the ground in the local area to become charged by induction.
I would say crouching is safer, although I am not sure. From what I hear, crouching makes you a smaller target, and if lightning were to strike near you, it could only go through your ankles. But lying down, especially when wet, means that if it strikes near you, you can still get it going through your whole body . I am not sure if this is true or not, what do you think? Thanks for uploading this by the way!
@derekowens i have one question Mr. Owens...it may sound a little bit silly, but i was wondering..you say "pointy" things at an open area charge more easily...does that mean that if a person is standing at a large area during a big storm (and assume he is the only "pointy" thing out there),and he decides to lye down to the floor,( so that now he is one with the ground),would that decrease his chances of being hit by a lightning???
Thanks a lot for the video. Can you tell me why the visible light from the lightning? I mean, Can the lone movement of electrons from the cloud to ground emmit electromagnetic waves? As far as I know, electrons cannot emmit light unless they shift from a high energy level to a lower one. Shouldn't be there some kind of ionisation of the air molecules and thus random recombination process between ion gas and e- and that explains the light? Just my personnal guess but I m not a real physicist.
@derekowens wouldn't it be much safer if a person on open ground covers himself with an insulated rubber blanket.........so that it wouldn't allow electrons to make any direct contact with our body......
''Note that in a capacitor this is typically not the desired result'' hahah I know It was an accident but a truly interesting one. Thanks for the reply.
You've got the charges all messed. The earth's surface is negatively charged and the aether ("sky") is positively charge. Also, the bottoms of the clouds are negatively charged and the tops of the clouds are positively charged.
That's right. There are lots of theories, and I believe the current accepted theory describes a "leader" coming from the ground and meeting the bolt coming down from the sky, so the path through the objects on the ground is determined by the leader. But this video was made in '09 and I would need to study up on the more current research.
That's an excellent idea, and it would definitely work. Just keep your metal boots on the ground. You could even hold your lance pointed toward the sky. Just stay of the horse, though. If you were on the horse when it struck, you would be serving cooked horse for dinner.
first thank u for your explanation second sorry about my not that good english :) but i just wanna ask you a question if don't mind can you explain why it is said that light don't strike twice on the same spot?? can you send a massage to me explaining that sir?
I am 67 yr. old & I finally know how lightning is formed & works! Thank you
I work for a lightning Protection company. I came to look for something I could use to explain to new hires. Great job on the video man.

Hey man, I've quit playing golf because of you
Wow speechless, this is tremendous, better than my physics textbook, i tip my hat to you sir.
This is definitly the best explanation.
Thanks! Actually, lightning can strike the same spot twice. There's a place near my grandmother's house that has been struck at least six times. Tall structures such as building and bridges can get struck multiple times during a single storm. The idea that it won't strike the same place twice is simply a myth.

Water takes a lot of energy to heat up so you need to balance the ratio
If opposites attract, why are there protons at the top of the cloud, and electrons at the bottom.
Shouldn't they attract and meet up in the middle?
Good question, or unless the attraction forces of the protons in the ground, tree, car etc are pulling the electrons in the clouds toward its bottom.
Precious adorable you're correct
The electron in the cloud are being attracted to the protons in the ground, so the electrons are pushing at the edge of the cloud to get to those protons

This video is really useful when u study physics. Thank u for making it.
I was struck by lghtning on my sailboat just as the anchor touched the ground, how do you explain this?
There is lightning right now , Thank you sir .
The direction of the electric field is from the positive electrode to the negative electrode. So are you saying that the flow of the electrons is OPPOSING the force and direction of the electric field?
So in an open field, with no place to go and trees are dangerous, is it best to find a cave or lay flat?? This way to not be that pointy attraction?
Why negative charge in lower side in thunder but not positive
Good question. I read the friction theory in a NOAA publication, and also in a book on lightning (can't cite the source from memory, sorry). Friction is well know as a means to separate charges, but it does seem odd to imagine it occurring between water and ice particles.
I don't know about *converting* all of the sunlight to UV, but catching the UV before it enters the atmosphere, such as with the solar panels on the space station, certainly produces power more efficiently.
So the lightning we see are movement of electrons?. or the radiation from electron jumping from a molecule to another?.
When lightening is coming down its finding its pattern to fall into place in order to hit a point the “matrix numbers” is the grouping of direction
phenomenally excellent ... Love you
what is the cause of light and sound during thunders ???? why dont the transfer of charges happens like in wires without light.....?
This clip is mistaken on one point: Things that are pointy do not have a higher positive charge. The air is insulation and taller things have less insulation between themselves and the charge in the cloud making them the prime point to arc a discharge from the clouds.

Gauss was able to show this (Gauss's Law) and this particular idea is embodied in Maxwell's Equations, which are foundational to our understanding of electricity.
Okay now this is epic.
How can the ground get charged by induction if the cloud is not touching or even remotely near the ground?
Nice drawing Mr.Owens

positive charge moves towards negative . Hence ground -> Cloud
Thanks for your explanations.
thank you so much. I have question can we be safe to walk in storm if we were a thick rubber shoe? Or will it be a suicidal act?

Lying down in the field should be safer than standing up in the field. Although seeking shelter in a building or a car would be better.

I think it’s possible because of the metals used in them for creating colours and thus the electron exchange between those particles and negatively charged atmosphere .
That's actually really hard as they contain really less amount of metals for the coloring and that amount can't handle the huge charge .
And I'm not sure metal's are the only things that can be used there
Non metals might be useful too🤨
@@ChandraMauliChaubey I’ve waited 3 years for this 😅

In a lightning Storm the most suggested option is to not stand up, stay laiying or seated down and far away from metalic or electro conductinle materials..,
Animals almost never get a Lightning strike due there shape converts them in not electrical conductibles.., by 4 legs walking,..
Does anybody know anytin4 about an irrational fear of litenin?..i`ve met sveral intellicent adults(usually female) sufferin from wot seems like a ysterical and paralyzin fear of tunder n litenin,despite knowin and understandin science involved .
i need it for my science project + i am following you
+Ernest Cheong Mee too!
It does help :)
@Derek Owens what program do you use to make videos like this? They're really good
if you find the answer, can u email me, keigneugebaur@gmail.com?
Why does the positive charge go to the top of the cloud, and negative charge to the bottom?
opposite charge attract
parul bhutra that doesn't answer the question at all
www.lightningsafety.noaa.gov/science/science_electrication.htm
It’s because the electrons (the negative charge) is attracted to the ground, which is why all f the electrons are pushing down at the edge of the cloud. The protons (positive charge) don’t move, but are just spread evenly throughout the cloud
What countries in South America have such high levels of lightning? Is Ecuador one of them?
Eman On Very cool! Thanks for the link.
Lightening can also come up from the earth!
Yes! Because somehow the earth can be both positive and negative charged and not short circuit itself!
I think that it's very clear that something is wrong with this explanation.. it doesn't work.
what about the positive charges left out in cloud and negative charges went beneath earth surface ???
when Ice crystals hit each Other and make negative charges at bottom and positive charges at top of cloud why they don't attract to each other in the same cloud to become neutral ??
Hai thanks for ur video. i still have one doubt. how tree and house getting charged though they are insulators? why not electrons on top of the car moves away and make it positively charged by induction?
Thunder and lighening in the clouds dispurse water and icegiving them degind shape.
I.e small balls of ice and thiner lines of water. Right?
So, clouds and rain have no relation with evaporated earth waters. Right?
Defined shape, very highly defined shape and dimension of snow and rain water , predefined sapes of snow and rain water comes from the creator sources, intelligent works, not from charges. Right?Thanks.
Whats the best way to attract lightning cheaply because I would like to observe it up close while in my car with some quick setup like maybe a iron bird bath with a couple of star shaped helium balloons tied to it. The string would of course be long so as to make it the tallest object out their and I would deploy it in a open field to increase the chances of a strike. I know I do this at my own risk so what do you think? The bird bath would have a stand rather then being hammered into the ground
So laying down flat on the ground should increase one's chances of survival if nothing else is available ?
Yes, I believe that is correct. You would have less charge concentrated on you lying down than standing up.
Your clouds looks like my grade 1 drawing of the leaves of the tree.
The answer to that is pretty complicated. If I remember correctly, the concentration at the points follows as a result of Gauss' Law, and that requires at least a couple of semester of calculus to prove. I don't know of a simpler, more intuitive explanation, but I'll give it some thought.
Very nice explanation. Have a happy 4th.
This is beautiful 😍
Very good explanation
This illustration isn't 100% accurate is it? Doesn't ground strikes usually come from both the clouds and ground (positive streamers), meeting somewhere in the air?
If I understand it correctly, it can go either from cloud to ground or from ground to cloud, and a typical bolt of lightning will involve several strokes back and forth. I don't think it would meet in the middle, though. Also, however, it is my understanding that this is something that is not completely understood and is an area of active discussion and debate among scientists and meteorologists.
No it is very inaccurate one tires don’t insulate a cars or trucks metal is in tires it not just rubber, and a vehicle can be struck. Also lighting does not go one way you have neg downward leader and a positive leader pos goes up neg goes down. And they meet the light you see travels up.
6:00 - ...'it will sound like static'... ...It is static, isn't it?
Thanks so much.
Thank you so much for the video! :D Question: Is that the same effect when the two plates of a variable parallel plate capacitor touch? Because one is negatively charged and the other one is positively charged. I observed at the lab that when the two plates touched at a potential of 30 volts approximately I could see little purple ''lightning bolts''. Is that analogous to a negatively charged cloud and positively charged object on the ground as you mentioned in the video?
Now we will talk about lightning. You see done clouds here. What you are seeing is just the bottom edge of the clouds. Thunder clouds can really be very tall-several miles high in many cases and weather inside the clouds the movement varies up and down can cause movement of charge inside the clouds and you can get a buildup of charge positive charge for example at the top of the charge and negative charge at the bottom. So I'll draw some negative charge here representing a bunch of negative charges building up at the bottom edge of these clouds. And again this is happening menopause weather inside the cloud moving inside the cloud. The cloud is basically broke polarized
What you see here is
You talk about charges but WHAT ARE charges?
Your "prrrrrrr" sound makes me laugh so hard.
great videos
But Ground is a zero voltage reference point right? so how charge could develop on ground?
As a general rule that is correct. The ground is the reference point and is considered zero voltage. This changes during an electrical storm, though. The charge on the cloud can cause the ground in the local area to become charged by induction.

I would say crouching is safer, although I am not sure. From what I hear, crouching makes you a smaller target, and if lightning were to strike near you, it could only go through your ankles. But lying down, especially when wet, means that if it strikes near you, you can still get it going through your whole body . I am not sure if this is true or not, what do you think? Thanks for uploading this by the way!
So simple! Thanks!
@derekowens i have one question Mr. Owens...it may sound a little bit silly, but i was wondering..you say "pointy" things at an open area charge more easily...does that mean that if a person is standing at a large area during a big storm (and assume he is the only "pointy" thing out there),and he decides to lye down to the floor,( so that now he is one with the ground),would that decrease his chances of being hit by a lightning???
Thanks a lot for the video. Can you tell me why the visible light from the lightning? I mean, Can the lone movement of electrons from the cloud to ground emmit electromagnetic waves? As far as I know, electrons cannot emmit light unless they shift from a high energy level to a lower one. Shouldn't be there some kind of ionisation of the air molecules and thus random recombination process between ion gas and e- and that explains the light? Just my personnal guess but I m not a real physicist.
Very good explaination...
Can we generate electricity from a lighting? thanks.
amazing explanation, before i watch this i thought the advice dont stand near the tree during a thunderstorm was bull**** 🤣
@derekowens wouldn't it be much safer if a person on open ground covers himself with an insulated rubber blanket.........so that it wouldn't allow electrons to make any direct contact with our body......
Physics with Bob Ross. Love it.
EXCELLENT SIR 👍
''Note that in a capacitor this is typically not the desired result'' hahah I know It was an accident but a truly interesting one. Thanks for the reply.
This was so helpful. Thanks ⚡️👏
You draw good man
Thanks for the knowledge
You've got the charges all messed. The earth's surface is negatively charged and the aether ("sky") is positively charge. Also, the bottoms of the clouds are negatively charged and the tops of the clouds are positively charged.
This is still a theory right? My textbook said there are many different theories for lightning and this one is shown
That's right. There are lots of theories, and I believe the current accepted theory describes a "leader" coming from the ground and meeting the bolt coming down from the sky, so the path through the objects on the ground is determined by the leader. But this video was made in '09 and I would need to study up on the more current research.
Needed a refresh on how this works, thanks.
Isn't this to great a distance for induction to happen between the clouds and the ground? Seems absurd.
So storm paths arent random?
That's an excellent idea, and it would definitely work. Just keep your metal boots on the ground. You could even hold your lance pointed toward the sky. Just stay of the horse, though. If you were on the horse when it struck, you would be serving cooked horse for dinner.
Informative video...pretty nice..
It was a good lesson
How does lightning find the easiest path to the ground? I'm a programmer, and that sounds like a lot of processing to me.
first thank u for your explanation
second sorry about my not that good english :)
but i just wanna ask you a question if don't mind
can you explain why it is said that light don't strike twice on the same spot??
can you send a massage to me explaining that sir?
