After your Aerotechnics™ cannon has been loaded with your choice of product, a Backpressure Cap™ should be placed over the end of the barrel and secured with tape. When the cannon is fired, the Backpressure Cap™ works in tandem with the Lifting Cup™ to build pressure, until finally the cap blows off and your payload is lifted high into the sky. Caps should be secured with masking tape (AE60), unless your product directions indicate otherwise. Pack of 12.

When making your purchase, be sure to choose the proper size Backpressure Caps™ and box quantity for your needs from the drop-down list.
