Build an Overhead Water Rocket Launcher Part 1 Introduction

how long does the rocket stay up in the air and how long does iit take to come down?

Very Nice.I am happy that these actives are still alive. I see many kids playing
Video Games,but these video games don't give you knowledge.These experiments will give you knowledge and you will be able to make your new inventions, in future.

sciencetoymaker I want to ask you that can i reuse this launcher.I mean i will shoot the bottle and then I will fill it again ,can i use it again?

Yes, you reuse it. I have launched thousands and never had one wear out. You reuse the bottles over and over, too.

Don't be an ignorant old fart. There are many games that teach problem solving and logistical thinking.

Also, instead of a flimsy pop bottle, a spring would work far better and take less space.

Your comment is not so impressive.....

However it would create an issue that springs because of how thin they generally are would be too loose themselves. And using a larger spring would only make it harder to use. Sorry, I have a bit of firing mechanism knowledge.

Thank you Very, Very much! I have been looking for launch ways to launch it without losing pressure. Thank you véry much :D

i made one for school to dose the whole state make one?

i made one for physics class it worked great

My brother built one, its awesome! :D great video!
