Lever- Catapult

My simple machine is a lever, I am making a Catapult. Catapults are used to forcefully launch things, mostly in the military.

Supplies

• 8 rectangular popsicle sticks, size does not matter
• 2 thick, medium sized rubber bands
• 3 small rubber bands

Step 3:

• The your last Popsicle stick in the center on top of the stack

Step 4:

• Place one little rubber band criss cross over both the top and bottom center Popsicle sticks. With the stack in the middle (which should be how it already is)

Step 6:
