I won my science project at my school thanks sci guys

Just did this with my kids and had so much fun. Thank you for you work!

I'm doing this for my science project. Thanks sci guys I can't wait to do this

You guys have given me the best explanations on experiments like these

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 ;))

I got a number one at my school for the bottle rocket contest! HUGE THANKS!❤❤❤

Perfect for our homeschool unit. Thanks so much for sharing!

Thank you . My kids loved the rockets!

The white coats makes it look like a Gary Larsson scenery. ;)) liked it very much!

I did a perfect school project thanks to you ski guys

The pump part helped alot

Great video, my 8 yrs old kid loved it

Thank you for this idea. I’m using it for a makerspace

Very good video 9YD loved it.

Thank SciGuys, now I have an idea to how to make one for my school project.

love it !!!!!!!!!!!!!!!!!!!!

❤ This is too great

Great work , guys. Good fun and science.

thank you very much for your responds

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.

very nice!

thanks ! I will use this for my homework :)

*I SUBSCRIBED your channel bros and turned the post notifications on. Awesome experiment bros. Love you brothers from Pakistan.* ❤

I loved my water rockets when I was a kid. So fun. I remember learning, from Robert Heinlein, about reaction mass. I sort of understood we were dealing with a Newton's law.

Nice video needed help from my technology project

Omg thank you so much you saved me from failing my science project 😂❤

Wow, amazing :O

nice video man, im gonna try this!

thankss....it was a gr8 help

Super I love this experience❤

wow thanks guys, i got an A+ for my work

this video and this idea are amazing!!!

this is amazing

I wanna try it !!

I receive honors at my science proyect. Thank u guys.

Hey sic guys, you guys really helped me out on my science project, thxs :3

hello, i liked your video. it has all the explanation. but how does air pressure affect the motion of the water rocket. and how do we measure the air pressure in this experiment?

I like this one is so cool

Wow great idea with the tire pump this is perfect for my chemistry class.

Thanks guys

I have a small question, since I live in a place where it's kinda hard to find these materials, may I ask if there is a substitute for cork? Like a material similar to cork, but not too hard to find?

good stuff

Super cool vid man ❤😂😊😅😮😮

AWSOME

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

good video

good job

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!

Thanks science guy, I subscribe to you guys

Oh golly gosh I’m so grateful for this, I’m doing this for science and u gave me all the answers. Thamks

This video is perfect for explaining how a bottle rocket works to a 3rd grader. Thanks.

Thank sci guys! I am doing this for my project!

Love from Vietnam.

I'm using this for my project thanks guys :)

Thanks a lot for the video! I wonder if there's a way to calculate how much water and pressure are needed (or else?), when we aim to hit a target in a particular distance. Anyone ever experimented with this? Thanks in advance.

hiii!!!! what is the function of the tennis ball? what happens if you don't use it? does it go further?

Thanks

THANK YOU FOR THUS

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!

Is styro okay instead if foam core board or same thing?

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?

SICK MUSIC!

Thx helped a lot in school project

Sir, What can i use as an alternative of foam core board?

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

what can i use as an alternative for the cork

thanks for this imma use it for my science project!

Nice video, actually we have a project to make a rocket launch and I like your video how you describe so much stuff in a short period of time and well detailed. I have a question that from where can you get form cardboard that you mentioned in your video?? Will it be available at Walmart or dollar tree or there is a specific store??

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

Can this be placed vertically and will travel far?

awesome i wish i could make one

I am going to try this in my science project! Also Facebook isn’t famous anymore

Wooow thxs alot for the video helped me Lot on my science fair

gang gang design guys, but is there a substituTe for a cork?

Great

what size corks do I need for a 2 liter bottle?

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!!!!!

I'm going to try this on our science project i hope it works we only have 2 chances Wahhhh :> Thank you.

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!

Is there any replacement for a cork

could it be possible to use a chemical reaction to generate the potensial energy to launch the rocket

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?

What can I use instead of a cork?

How do I keep an egg safe in this? I'm doomed in physics right now if I cannot figure this out LOL

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?

So, can you reuse the bottle and fill it with water again?

Can this experiment demonstrate of 3 laws of motions/force by newton?

I Subscribed

Hi sci guys I am using it for my sci competition can you tell me why did you use the ball

Cool

I wanted to know if this could be spray painted after assembling to give it more of a real rocket look?

I want the rocket go higher and go down longer ? How do I do that ? It competition in my class

I couldn't find a cork, what another item that could replace it?

Hey, does anyone know what the most aerodynamic 2L bottle is for this experiment?

What if you didn't just compress air, but also fill it with baking soda and vinnager?

Doing project in school for project with my friend thanks for teaching me how to do it

does the amount of water matter how high the water bottle rockets can reach it's distance? please answer thank you.

amaizing rocket!!!!!! ^=^

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! :-)
