The Leprechaun Catcher
By: Katie Schutte
What Needs to Happen
My trap starts out with a sign pointing right. Leprechauns aren't good at following directions, so he should go left. After he goes left he will see a green pot with gold in it. Once he goes and tries to pick up the gold the box will fall. Finally the leprechaun will be stuck.
My simple machine is a wheel and axle. It works when the leprechaun grads the pot of gold. It will let the box drop.
