Paper Rocket Launcher

DIY Paper Rocket Launcher Tutorial. This is a great project to do with your kids or with a youth group. The launcher uses compressed air to launch paper rockets farther than you would expect. Most paper rockets can withstand 20-40 psi, but if you make them robust you can crank sometimes withstand 60-100 psi. Ideal activity for kids 8 to 14 (and for parents too)!

Thank you so much for this video. I followed this how to and made a launcher for my science class. We did some research, made a first attempt, trialled, and then made a second. They loved it. Thanks so much for making and posting this.

Glad it helped!

Wow, super neat!

[@ScienceFunInnovations]

Glad you think so!

Nice..Try and land them horizontally like I normally do. It's challenging and fun.

[@ScienceFunInnovations]

Thanks for the tip

Awesome video! Trying to make one of these for our cub scout troop. Did you have to alter the sprinkler valve at all? When I press the button, it seems like it slowly pushes out the air, but if I put my finger on the tube (to give it back pressure) it pops and gives me a solid burst of air. Any ideas?

[@ScienceFunInnovations]

Make sure you have enough voltage to open the valve. I use 2-9V batteries in series for 18V.

@@ScienceFunInnovations what do you mean when you say you worked the batteries " in series"? Also how do you connect the wire to the top of the 9v batteries?
