This little catapult is fun to play with on its own, and even more fun to surprise friends co-workers with. A nice little device to stand guard in your doorway.

Supplies needed:
1 Large Eraser
3 Paper Clips
1 Popsicle Stick
1 Spring (this could be from a broken electronic device in the battery compartment)
1 Chapstick Cap
Hot Glue
Strong Scissors
Pliers
String or Dental Floss for a Tripwire

Be careful not to load anything sharp into this catapult when the intent is to fire at a person or animal. You'll put your eye out.
