Build a Paperrocket-launcher with a few students, from an idea/project of Sonicdad. Decided to make a schoolproject out of it, by letting the students design and test all kind of tailpieces.

We are still in the testing-fase, but this is an impression of our first real testingday: https://youtu.be/drMr5mxI0Aw Students reactions were great!

And this is the Sonicdad instruction for the launcher, we changed a few things, but you'll get the idea. http://www.sonicdad.com/project-details/paper-rocket/
