Paperrocket tailpiece

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:

Students reactions were great!

And this is the Sonicdad instruction for the launcher, we changed a few things, but you'll get the idea.
