I won my science project at my school thanks sci guys
Cool beans!!
Wish me good luck, I will try to do the same next week
Hello
😅 Me too
Forgot the comma
I'm doing this for my science project. Thanks sci guys I can't wait to do this
Same 😅😅

okay this is gonna be so creepy but did you go to scholarly
sorry if you didn't i can embarrass myself really well
Monica in reply to your question, are there a way that you can make the rocket travel higher and stay up in the air longer?
There are a number of ways. One way would be to build up more air pressure inside of your bottle. To do this you would need to use a much tighter fitting cork or build a release mechanism for your rocket. A release mechanism would hold the rocket on the launcher until you pull a string or press a button, and would work the best. A tighter fitting cork is much less effort but may not work as well. Be careful with both of these methods because too much air pressure inside the bottle could cause it to explode before it even launches.
Another method would be to run tests to find the perfect amount of water to add inside your bottle. If you can find enough water to make it go high, but not too much that it weighs down your rocket that will also increase the height that it flies.
A way to slow the rockets decent would be to design and add a deployable parachute. If you want to do this method, I would suggest searching on google for tutorials.
There are probably more ways to get the rocket to go higher, if anyone has any suggestions reply to this post. I hope that these ideas will work for you and let us know how you do in your competition.
Thank you I going to try this
Monica Nan Sounds great :) Let us know how it turns out.
The Sci Guys Hello we are about to perform this experiment.... Can we use Soda (Sprite, Coke) like that to make the rocket more higher?? Thank You!! Needing your answers ASAP
darren That is exciting that you are doing this experiment. I doubt soda would change the height the rocket would fly. What would make it higher is adding more pressure and finding a perfect balance between pressure and liquid amounts.
The Sci Guys I
You guys have given me the best explanations on experiments like these
Didier Serrano Moreno You're most welcome.
A couple of safety things I feel should be addressed in this video- when cutting anything with a scalpel or utility knife you should be using a steel ruler, this not only protects your fingers from the blade, but it also ensures that your lines will be straight and not wiggly. When cutting with a knife you should NEVER cut towards yourself, always cut away or at right angles to your body- if cutting through something tough or thick you can be putting a lot of pressure onto the blade and once it is free from the material it is incredibly easy for the blade to fly into you if you are cutting towards yourself- I got a scalpel blade in my leg cutting in this way- it's a lazy and unsafe method Otherwise, an awesome video- I hope to use this in teaching a class of p7's. Thanks!
shush no one cares
Hello
Thank You, Guys! This really helped me on my Science Project and helped my parents understand better :D You had no idea how hard it was to explain this project ;))
Thank you . My kids loved the rockets!
B-R-U-H
Hello
I got a number one at my school for the bottle rocket contest! HUGE THANKS!❤❤❤
The white coats makes it look like a Gary Larsson scenery. ;)) liked it very much!
what can i use as an alternative for the cork
Bottle cap or cotton?
What is the use of tennis ball ? Pls reply me ASAP i need to present it in class 🥺
it's great I tried it and it was amazing I am part of space club and they always told and shoe hydro rocketry but they never told how they do it I am now very happy as I can create my own hydro rocket now
+G Kaur great to hear you are having fun with it
The pump part helped alot
Suppose I would want to add a parachute to the to.. how would i do that and what effect would it make to the overall experiement, like would it effect the height the rocket goes and how would the parachute be activated... any ideas Sci Guys?
+Adil Mehra Also suppose we would want to put another liquid in the bottle, suppose coke? would the rocket go higher as there is a much more reactive liquid in the bottle?
Hello
This video is perfect for explaining how a bottle rocket works to a 3rd grader. Thanks.
Toni Jenkins I am really glad you found our video informative!!
also in our water rocket challenge,the winner is measured by the range at which rocket lands instead of height,so would u suggest any improvement in aerodynamics of rocket or rocket launcher that would make it land farther
brhamjyot singh sandhu If you are building a rocket and looking at range, I think that angling it at a 45 degree angle will help to get the distance. You may want to play with the weight of the nose cone because if it's too heavy it will pull it down quickly and if it's too light it may not move the centre of gravity enough to keep your trajectory.
hiii!!!! what is the function of the tennis ball? what happens if you don't use it? does it go further?
My daughter is going to do this for her school science fair. I think we'll do a few attempts at home just to be sure she has a good idea how to do it and what to expect. Should we use a different bottle each time or can we reuse? Also, about how much radius would you recommend for launch to safely be away from cars and the school building? Thank you, great video!
Lisa Umbilal That is exciting!! You can use the same bottle each time as long as the bottle is not ruptured. The distance you should be away from the school and cars depends on the direction and strength of the wind. If there is just a light, then 50 feet should be enough but as the wind gets stronger that distance grows. Also our build of rocket is pretty light and I cannot see it doing much damage to a vehicle or building.
You could also use different size and shapes of bottles, as well as different amounts of water, to find out how they impact the height that can be reached.
hey sci-guys i go to a class that's all about water bottle rockets and one of my friends got it up to 810 ft. mine was 435 ft but we used a special launcher that my teacher designed himself. maybe you guys can use a launcher! :-)
Erika Ojeda That is a really great height!! I like your idea of making a launcher. We will probably do a follow up episode on how to make a launcher for your rocket. Thanks for the idea.
@@TheSciGuys hey sci-guys what can i use as an alternative of foam core board and cork??
@@srishtisinhasinha4142 Cardstock and a waterbottle lid.
can I use it as a project of recycling
can I use it as a recycling project +Sci science
+gumdrops drops maybe? You are re-using materials, I would guess if you used all previously used materials but it would depend on what the goals of the project are.
Hey i tried out various different bottles- 400ml, 600ml, 1L, and 2L. for me the 400mL water botlle rocket went the highest
How much water did u put in the 400ml water bottle
@@Ishaan-lb8pu about 150ml-200 ( i think 150 is the best )
thank you so much
Thank SciGuys, now I have an idea to how to make one for my school project.
Juan Jimenez sweet
I want the rocket go higher and go down longer ? How do I do that ? It competition in my class
Why do you need the water? Won't the air pressure produce the same thrust!
I was thinking about this too and after a few ideas I landed on mass. The water is forced out of the bottle but it has more mass, so it is doing more than if it were just the gas.
Basically, since it takes longer to get out of the rocket, it is applying a longer acting force so the momentum change is different
Hey sic guys, you guys really helped me out on my science project, thxs :3
Jacob Cope You're very welcome :) Glad we could help. If you want to help us out you can share our videos with your friends and encourage them to subscribe. Also let us know if you have any suggestions for episodes.
The Sci Guys would a raw egg survive the fall if it is in the rocket in a capsule?
Manuel Martinez you need to create a cushion so that a lot of energy goes towards deforming the cushion rather than into the egg. A great way to understand this is by researching momentum and impulse.
*I SUBSCRIBED your channel bros and turned the post notifications on. Awesome experiment bros. Love you brothers from Pakistan.* ❤
gang gang design guys, but is there a substituTe for a cork?
How high does the bottle usually go?
Hello
Can this experiment demonstrate of 3 laws of motions/force by newton?
nice video man, we actually are competing in a different competition,in which we've to blow cork in a test tube as far as possible without breaking the test tube,it would be of great help to us if u would suggest any chemical rxn or method that would do the job
brhamjyot singh sandhu Well there are a few options that are simple. What you really need is something, solid or liquid, that will turn into a gas. You will also have to play with how snug the cork is so that it's snug enough that it will still shoot out before the glass breaks. Off the top of my head a few items you could try are baking soda and vinegar or putting a piece or two of dry ice in there. The dry ice may weaken the glass because of it's temperature but might be a good option. What types of methods were you thinking of using?
Just did this with my kids and had so much fun. Thank you for you work!
thanks ! I will use this for my homework :)
We'd like to do this with our whole school- like 500 kids. Have you tried 16 oz water bottles? it would be much easier to get 500 water bottles, but I don't know if they are strong enough to hold up to the pressure? What are your thoughts?
"fwuuuuuuuuuu im a rocket"🤣
very nice!
Hi sci guys I am using it for my sci competition can you tell me why did you use the ball
I'm going to try this on our science project i hope it works we only have 2 chances Wahhhh :> Thank you.
Is there any replacement for a cork
Would adding more air but less water affect performance positively assuming they are at the same pressure?
+BlueLightning Films It could for sure change the performance. How it will change it then I am not sure. You will need to test it.
hi can i use cardboard for the fins for science project Im am testing to see if a rocket with hot water will go higher than one with cold water.
Is it okay to use card boards on the stand of the bottle rockets and what if you put little more water on the bottle? will it go a bit more higher?
chuleng voluptous Yes it's ok to use cardboard but you may need to replace it if it gets too wet to hold up the rocket or if it sends the rocket in strange directions when wet. You can try adding more water, or removing some to improve the height. It's something that you will have to try out and see what works best.
dear sci what t type of bottle would make it go higher
what's the purpose of the tennis ball?
Can this be placed vertically and will travel far?
Can u tell me what is the Materials?
im do a project at i only can use carbonated water bottles and I also have to fight air resistance!! what Im asking is what kind of bottle I can ues?? and what can help the rocket stay longer in the air!!!!!
Great work , guys.
Good fun and science.
+Aorion On Thanks!!
Doesn't that tennis ball add mass? Seems there should be way that add's less mass
Nice video needed help from my technology project
What can I use instead of a cork?
What's the function of the tennis ball?
In my science class, we have to build one of these; we will be graded on how high it goes and how well it stays together when it lands, any tips?
jackie bucio Ours kept together really well. Test your rocket before hand to see how much water will give you the best height. Try to fight light and sturdy material for the fins. Ours were a little too large for optimal flying so you could probably make them smaller.
hi, I have a similar lab in school project, we are going to be judged based on how high it reaches and its speed. We need to have a nose cone at the top, and fins. What kind of fins can help my rocket go fast and high, basically reduce drag. For my nose cone I'm using a parabolic cone bsed on the reviews I have seen. What kind of fins and nose cone can help reduce drag and make it fly faster and higher? I'd like to know what other alteration can help my rocket go faster and higher? Pls reply asap!
wow thanks guys, i got an A+ for my work
Trương Đức Hiếu Congrats :) We love hearing about the academic achievements of our viewers. Keep up the great work!!!
Can u plz help me out with the amount of water we should take in 2l bottle for highest flight
what is the ball for? weight?
love it !!!!!!!!!!!!!!!!!!!!
How high did it go
o miles
thank you very much for your responds
Guys can i replace the tennis ball with somthing else?
What if you didn't just compress air, but also fill it with baking soda and vinnager?
Love from Vietnam.
Sir, What can i use as an alternative of foam core board?
Thanks
but won't the plastic bottle just explode if the bottle is too thin?
Wooow thxs alot for the video helped me Lot on my science fair
Noureldeenhany Aldeeb You're very welcome :)
I think its a cutter not a utility knife........pls..correct me if I'm wrong
+Francess Jewel De Guzman If you google utility knife it will show you that it's a utility knife. The terms may be interchangeable but where we live it's called a utility knife. I have also seen it called a box cutter but those are usually smaller and the blades look like razors usually.
+The Sci Guys oh...okay...thanks....your the best!!^_^
Francess Jewel De Guzman You're welcome :) and thanks
Very good video 9YD loved it.
Devan Navaneethakrishnan Great work!! Thanks for letting us know about your success. Do you know approximately how high you got the 400ml bottle to fly?
Is this rocket based on aerodynamics or related to aerodynamics
Wow I bet I would get an A on this invention igoing to try it!
Jane Ashcraft Sounds like a great idea!! You should make one, let us know how it turns out and share a photo of it with us on Facebook.
Thanks The Sci Guys I think it was a great idea to tape a tennis ball on the tip instead of a cone! When it hits the ground is it supose to bounce when it hits the ground?
Jane Ashcraft It tends to bounce when it hits the ground, nose down. The goal with the tennis ball is to help balance the weight and shift the centre of gravity of rocket. The tape over the ball helps to produce an aerodynamic nose cone. It's an added benefit that the ball can also partially protect the rocket and absorb some of the fall.
The Sci Guys oh I tried telling my group tht and they were clueless!
Ill post the video by the first week of may
what size corks do I need for a 2 liter bottle?
I am making a bottle rocket for a competition, what are the best type of fins for this?
Hi! I would like to ask something...does more water cause the rocket to fly higher? If not, what does? I'm about to try this for our project in physics and I'm wondering what adjustments should I do to make it fly higher.
And btw, what can we use as a substitute for the cork?
I think no(i google it and found the best composition is 33% of water)
So im doing this in my science class but the challenge is that i have to add an egg to the rocket how do you think i can do that, because the egg can't break part of the assignment is to see how high it goes and how good the landing is going to be. help me? Also any tips?
Nanci Melgoza Ooooo.....that is a tough one. I remember doing that in Junior high and most of our eggs broke. Maybe try making a pod for your egg with bubble wrap and a parachute. The challenge is to get the rocket high enough, and get the parachute to deploy early enough that it will open and slow the eggs fall. You could run some test flights with a golf ball to see if your parachute will deploy.
how big should the fins be? (in inches)
and is it possible to replace the tennis with another item
Clay Think
U could use clay
what can be a replacement of the tennis ball?
+Yuki dairo You could use foam or cardboard but you might need to add something with a little weight.
how high do you think the water rocket went?
Hi. Can i ask why we need tennis ball for this water roc2
I mean rocket
Do bike pump pins/nails have sizes? or just the same?
fire fly Nails will come in a variety of sizes but I think the bike pump pins are usually universal in size. Try and find a nail that is about the same thickness as the bike pin.
Wow great idea with the tire pump this is perfect for my chemistry class.
can someone please tell me what are those things need to make a bottle rocket?
why did you make use of the tennis ball
What's the purpose of the tennis ball?
+JuryFive Cinco The purpose is to shift the center of gravity of the rocket so that it will fly better. It will also provide a little protection when the rocket hits the ground.
❤ This is too great
This might sound stupid but why do you need water
Oh golly gosh I’m so grateful for this, I’m doing this for science and u gave me all the answers. Thamks
Hi, can I replace the tennis ball with clay?
+Nur Syasya Sure that will work to lower the center of gravity but won't work to absorb the landing as well.
I like this one is so cool
Could you add a parachute somehow
Yeah! Attach a plastic grocery bag tied with some string to the front with tape. Fold it up in a specific way, I believe the same as an actual parachute (a little too detailed explain here) and press onto the top of the bottle as it sits. it will unroll as it begins to fall and fill with air. Pretty cool
Super I love this experience❤
I just did this in my science fair but instead of a just a bottle I made it look like the Saturn v
nice video man, im gonna try this!
modemmod100 Sweet!! Let us know how it goes.
squirrels in the trees and the critters in the creek
How high did this rocket go?
Super cool vid man ❤😂😊😅😮😮
are their any alternatives for the foam board?
Raphael Macam You could use cardboard or a form of light plastic. You can use a lot of different materials but it's best to try and use something that is water resistant.
how is acceleration related to mass&applied force?
balance
Newton's 2nd Law of Motion, F=ma. Greater force will result in higher acceleration. The mass of the object will influence its acceleration as well. Greater mass will result in less acceleration while objects with smaller mass will result in greater acceleration. Hope this helps.
