First, find a block of wood, a clothespin, and old egg carton and a glue gun.
Give a couple of hints about how to use the glue gun safely.
Glue the clothespin to the block and the egg carton (or bottle cap) to the clothespin.
Do it again.
Set out an egg carton and see if you can get the ammo in the egg holes.
Learn physics. Laugh. Be thankful for the moment.
