Picture of The catapult with two pencils

The supplies are 5 popsicle sticks, a plastic lid, 8 rubber bands, 2 pencils. Attach a popsicle stick to a pencil using a rubber band – these pieces should be perpendicular. Do the same to the second pencil. Attach one more popsicle stick to the pencil, it should be perpendicular to the first one, too. Attach the two pencil constructions to each other using rubber bands. Attach the sharp ends of the pencils to each other with a rubber band. Place one more popsicle stick on the other end and secure it with rubber bands. Put a popsicle stick vertically and attach it with a rubber band but not too tight. Hot glue a plastic lid on top of the last stick and voila!
