Did anybody else realize she was extremely scared of it. Maybe it was because he said it was over 10000 Volts.
It's not the voltage that kills you, it's the amps.
Eduardo Alfaro True, but it will still hurt. He wouldn't try to kill her.... I hope XD
@@edjavas and how do you get enough amps to flow through your body? by raising the VOLTAGE
I made a capacitor out of aluminum foil and a 5 gallon bucket and lid.It blew a hole in the bucket, pencil eraser sized, and loud too. I have no idea of how much power that is but I would be surprised if a jolt like that wouldn't kill a person outright. I got shocked by a piece of plastic no larger than 12" x 18" 1/8" thick that was not even close to being fully charged and it took me maybe 20 -30 seconds to even remember my name and what I was doing. High voltage when used to charge things up like leyden jars and homemade capacitors is no joke and takes only one mistake to flat out kill you or your friends or family member. And time does not always dissipate the charge either, I have discharged a sheet of plastic over a month after I had charged it and it still had a scarey amount of juice in it. If you insist on playing like that do yourself a favor and always keep one of your hands in your pocket so if something does happen you are far less likely to have your heart in the path the electricity is likely to follow.In one arm and out the other puts your heart in the path. That is no guarantee you will survive, I wish I had read that somewhere early on, Not everyone will be as careful or lucky as I was early on. Best not to even go there on a whim.
I guess you could say she *sunglasses* felt a little spark between them
YYYYYYYYYYYYYEEEEEEEEEEAAAAAAAAAAAAHHHHHHHH
It's 3:40 am, and I keep telling myself "this is the last video, gotta go to bed....ok one more."
My 6th grade science teacher had one, I think it was a little different cause it had like a plastic or glass casing around the metal ball, and the purple line things appeared constantly in the casing, so what we did was we each got to so up and put both hands on it so that our hair stood up.. It was SO much fun! :D
thats called a plasma globe
My Brain: YOUR ASSIGNMENT IS RIGHT INFRONT OF U! DO IT!!!
Spangler: You know, it's scientifically proven that homework bores kids.
Me: Seems Legit.
When it's 6:45 and your still watching these do you just go without sleep?
bro is literally trying to sell the generator.
I like your show!
Why, that's the funniest dace I've ever seen!
@SingledMusicMan23 holy cow
@ibold1000 yes, yes she did
7:12 PM same ...
@puppyheartlove321 actually, she said shoot. You have to listen very carefully.
0:59 did i hear her cuss
I just study about it right now
she was so afraid and confused :D really funny :D
Static Electricity - Van de Graaff Generator
A Van de Graaff generator is a device that produces high voltage static electricity by accumulating charges on the surface of a large, insulating sphere. It was invented by American physicist Robert J. Van de Graaff in 1931. The generator works on the principle of electrostatic induction, which is the transfer of electric charge between two conductors in a closed system.
The Van de Graaff generator consists of three main components: a high-voltage terminal (the sphere), a belt or corona wire system, and a grounded metal base. Here's a brief overview of how it works:
1. A large insulating belt, typically made of rubber or Teflon, is continuously stretched from the high-voltage terminal (sphere) to a charged electrostatic generator, which is usually located at the grounded metal base.
2. The generator at the base produces a high voltage, typically in the range of 100 kV to 20 MV. This high voltage ionizes the air around the electrodes in the generator, creating a stream of positively charged ions.
3. These positively charged ions are attracted to the negatively charged belt, which is moving continuously from the generator at the base to the sphere. As the ions move along the belt, they transfer their positive charge to the belt's surface.
4. When the charged belt reaches the high-voltage terminal (sphere), the accumulated positive charge causes the sphere to become highly positively charged. This charge induces a strong electrostatic force, which can be observed when objects are brought near the sphere.
5. The high voltage on the sphere can be used to power experiments, such as making hair on an object close to the sphere stand up on end or creating sparks when touching the sphere with an insulating object.
Van de Graaff generators are widely used in educational settings, scientific research, and various applications that require high voltage and high charge levels, such as particle accelerators. They provide a visually engaging and interactive way to demonstrate and understand the principles of electrostatics and static electricity.
are you sure you are moving the right crank?
its great
de Graff and electricity. Reminds me of the Demon of Empire City
Yes,aslong as you can carry a current.
it is literally 3:40 am for me right now, going through the same problem
i used my hand instead of the ball. not sure about the amount of power though. it kinda hurts.
best pickup tool ever
CAN WE CREATE A ELECTRIC FENCE WITHOUT A CONDUCTOR (wires) ?
from this video , we can see that current passes through the air (non conductor)
Is it possible to create a electric fence above the ground by only two metals separated through a air gap ? like in VAN DE GRAAFF GENERATOR.
I think by developing this houses in forest regions can be protected from wild animals.
It's possible with lazers but for it to work it would have lethal charge.
HOLD ON A SECOND!!!!!!!!!!!! WAS THAT MRS.ADEMS
Oh Steve Stoop!!
must have been a
*sunglasses*
SHOCKING EXPERIENCE!
@ibold1000 i think she said shivers
"i know, i was lying", classic steve.
she has a perfect karen cut
#solid
Freak'n Magic ! . . . watch the "flirting sparks" fly. 😆
I went up stage in the science center and touched it xD It was F.U.N
i would have love to see her hair fly up. Just like it was doing it to me when i was young.
@ibold1000 i think she said shoot... but i could be wrong
Gud one I like this.............
1:38 "which hand do you use the least?" lol as if she has more than two hands. he should've said "which one do you use less?"
lightning help!
I played with that in my IPC class. Lol I really don't like static electricity
@ibold1000 she says shoot
@ibold1000 no she said shoot
@ibold1000 Ummm She meant that but I actually think she said shoot :p
so attractive
my life right now
@ibold1000 it sound more like shoot
@ibold1000 i think she said shoot.
this is john hutchinson experiment. or is it nickola tesla
im doing it right now
someones a lil touchy
oh steve don't stop please ohhhhhh
3:46 AM and I need to go to bed :D
Gotta love 9 news.
Her dace is so funny if you pause it at 2:38
WHAT HAPPENED TO THE BARBIE???
@ibold1000 No She Said Shoot '
@goffymew56 No the belt brushes againest a metal brush
When did she say shoot..?
this guy want to do some bondage i can tell!
I noticed that the hosts are always surprised.......hopefully that's an act
@ibold1000
she said aahh Shoot!
someone in my class last year in physics put their tongue on one of those while it was charged, it was bad
The guy just wouldn't stop, was getting worse every sec! Hold this ball, now touch the glob, now turning on the moter, now lets cranck it up, now stand on it naked with your privets touching, now stand in this water! LOL!
now its 120
i got told every second is a mile ive been lied 2
LIGHTNING HELP!
lol cool
I love how this science guy like to try to scare an intimidate Becky Ditchfield with science.
@ibold1000 Shoot... But I was fooled the first time too! :)
@ibold1000 She said "shoot" lol
the guy is a little frisky :P
@ibold1000 Why did that get 50 thumbs up? Wasn't it plainly obvious that she said shoot?
@ibold1000 shoot*
did that in shcool so funn
@ibold1000 She said shoot! (just in case you don't have enough replies)
I remember 5th grade. We did this in school as a punishment. He'd turn the motor on and he'd have ya touch it after it had been running for a minute. He, of course, had you touch it with a metal ball on a stick. The sound would be SO loud, that 99% of the people doing it would smack the Van de Graff generator, and zap themelves with 50'000 volts. The only reason you didn't get fried was because you stood on aluminum foil, and there was a wire leading to a light bulb.
i bet they're doing it
I dunno why, but i felt a little shock in me... O_O
i did this at school and touched a metal sink. lol
she said shoot
she's so funny.
-Bruce
no way i just read this and it was exactly 3.40 am here and im doing the same thing as you 0.0
playaaaa
She said stop touching me to steve
lol as i read this i realized its 3:39 xD
If one could make a battery that can instantly charge, i think static electricity would take off.
Did you know if you have heart problems u can't use one if these
0:58 did she say s**t on the news?
now to "shock" my physics teacher....
The fact u might not even go to school now is crazy
@ibold1000 no she sain "shout"
she said "oh, my shirt!" because she felt a tiny shock.
1:20 what the hell
i know how you feel
my friend Rama so confused
Assistant....
STEVE LET ME GO TO SLEEP
What?
Oh, get an electric given one a crank ones no fun
I said to myself, "I'll watch it for another 20 minutes..' It's been 3 hours..
