Step 9 Safety Restraint

Tie a strong nylon string from the base of the PVC to the Air Chuck. I added some glue in both places to help hold the knots in place. This does 2 things. One is making it safer for the little goblins who will be dropping their treats after this thing surprises them. And, along with the 45 deg cut in the PVC, helps keep your mask looking the same way each time you use it.
