How to Make a Popscle Stick Catapult

Rip the erasers into small chunks and pull the end cap off the back of a pen. Slide the ink tube out of the main pen tube.

Measure 2 inches down a Popsicle stick and cut the stick at this length with the scissors. Repeat. Measure and cut two Popsicle sticks at 1 3/4 inches in length. Set aside the leftover stick sections.

Glue the sticks together in the shape of a rectangle. Glue the remaining sections of the 1 3/4 inch sticks flat against the two 2 inch-long pieces at the bottom corners of the rectangle. These pieces are going to be the arm supports.

Cut a notch in the middle of the top end of each support arm measuring 1/3-inch deep and 1/10-inch wide with the scissors.

Measure 2 inches down another Popsicle stick and cut it at this point. Glue the ends of this piece in the notches.

Carve a small hole in the center of this stick with the tip of the scissors. Insert half of a rubber band through the hole. This half of the rubber band will now have a loop shape. Pull the other half of the rubber band down through the center of the loop.

Cut the pen ink tube 1 2/3 inches from the end and cut the spoon handle in half horizontally. Discard the half that is not attached to the spoon.

Tape the spoon handle to the center of the pen ink tube and insert the spoon through the looped side of the rubber band.

Push the thumbtacks into the stick that sits between the support arms until the points of the tacks go into the end of the pen ink tube. Set three eraser chunks onto the spoon and pull the spoon back to fire the ammunition.
