Plane Slingshot and hook

Wanted a new toy for my 6 year old son. We first tried the rubber band propellor but it broke quickly. Went simple and made a small slingshot and hook to propel paper planes instead.

1. Use some sticky tape to connect the hook to any of your own paper plane creations.
2. With some rubber bands attached to the slingshot, attempt to shoot your plane to the stratosphere ;).
