This is my entry for the pocket size contest. This neat little catapult will launch mints or other fun projectiles in a medieval and discrete manner. It only takes about 10 minutes to build, and is really fun. Enjoy.
Step 1: Materials and Tools
All the materials and tools you need for this project can be found around your home.
Tin (I used an Altoids Gum tin because it was small and compact)
Electrical tape (any tape will do)
Small piece of cardboard
Measuring spoon (or something similar)
