The Sci Guys: Science at Home - SE1 - EP18: Water Bottle Rockets

Welcome to the eighteenth episode of The Sci Guys. In this episode we will be investigating physical propulsion by building a water bottle rocket. We will show you how you can explore this topic at home with a bunch of simple household items and at the end you will have a fully functioning water bottle rocket.

Equipment and Ingredients:
Empty 2L Soda Bottle
Foam Core Board
Tennis Ball
Cork
Nail
Bike Pump
Packing Tape
Pencil
Ruler
Utility Knife
Measuring Cup
Water
Goggles
Lab Coat

I won my science project at my school thanks sci guys

[aerialimpressionsofPA]

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

[mathewomg]

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

[ashleypenn]

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

[冰激凌]

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

[HeinrichErnst]

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

[alessahall]

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 ;))

[didierserrano]

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

[qasimalitarartechnical]

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

[sabrinamorris]

Thank you . My kids loved the rockets!

[AhmadSalahAbdElMotagaly]

Great video, my 8 yrs old kid loved it

[commandeltd.]

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

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.

I did a perfect school project thanks to you ski guys

[sxdab]

Nice video needed help from my technology project

[rnlyn]

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?

[laylaz]

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

[juanjimenez]

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

[MikeEdwin-gssu]

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?

[elsami]

thanks ! I will use this for my homework :)
