How to Make a Water Rocket

This video will show you how to make a water rocket.

This video was specifically made for our Cub Scout Pack, but we encourage everyone to try these out! We have received feedback from around the world from people that have used this video to make their water rocket, many claiming they won their competition or received an A on their physics project... congrats!

If you are attending our event, we have the rocket launchers, you don't need to make one!

If you want to know how to make a launcher, here are some videos that we used to make our launchers:

My son tells me the night before that his bottle rocket project was due the next day. Ugh. THIS video helped us get it done and his rocket came in second as far as distance out of a class of 25 students. Yay! Thank you for such a helpful video! We used Play-Doh for weight.

Oh my gosh thank you- This is a huge part in my grade and the teacher of course isn’t helping at all and only stressing everyone out. Even though this was two years ago, thank you!

Awesome video, helped out alot! Our rocket went the farthest, in fact, it got lost in the woods, lol. Thanks again!

Thank you so much! The instructions my teacher left me weren't really that specific, so I really appreciate the video. We launch our rockets tomorrow, so hopefully it'll fly. Again, thanks for the video! If I can remember, I'll post my results.

Well done Greg!  Clear and simple step-by-step instructions.

Yaa, I got full information about water rocket and design of making parts. Superb explaination, I am very happy after seeing your video, in our college one of the competition is there and I will participate in your design and it would be the getting prize.

I had a science project about water bottle rocket and I didn’t know until few days before the launching day!!! Your video made it SOoO easy for me to understand and build! I made it inside the deadline and it went really high 😊😊😊!! Thanks so much I couldn’t have made it with your video!👍👍👍😀😀😀😁😁😊😊😊

It's really awesome hoping to get the first prize after watching this osm video❤❤

Bro thanks to you we broke the world record in australia

[arpithsampathkumar]

I love you so much, you deserve more subs. Gonna get the science boys to sub to this ASAP.

[ThunderStruck]

Thatnks dude! This helped me ALOT for my project for physics

[Ninja-xhlw]

Thank u so much that helped a lot.
First time making one for my sons school dew in a few days.
Know i need to figure out how to get the other stuff

[BossMan]

Was doing this project and kept messing it up but this video was so helpful!! Science teacher is giving us this project just before Thanksgiving break lol. Thank you so much, this video literally saved my whole project.

me like dis video so much thAnks Gregory

0:47 but what do you call those gradients smaller than inches in the imperial system?

[rowellanaanapot]

Thank you, Sir, But Can u explain how to launch it?

[KgfkarthiRocky]

Why you place a small ball in top of the rocket ?for some weigth????

[georgeboyce]

I feel very confident about my rocket through your confidence in the explanation

[sokpenglim]

May I know what is the purpose of adding the weight (golf ball). If I do not add weight, does it mean that my rocket can fly higher-ups? Thank you.

School project and I’m wanting to do it a different way then their showing so I’m confused a bit
