Step 5Holding the arm in place...
In this step we are going to make an insert that will fit over the spoon and in between the rubber band. This will allow for adjustments to the length of the catapult as well as aid in winding the rubber band.
To do this, cut a small piece of cardboard and wrap it around the base of the spoon. While still on the spoon, wrap a couple turns of tape for added strength.
IMPORTANT: Do not tape the cardboard to the spoon; you want to be able to remove the spoon. You want it to be snug but allow for movement.
