|Backpressure Caps™ Part #: AE61 Price: $3.00|
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 tightly 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 2-3 full revolutions of masking tape (AE60), unless your product directions indicate otherwise. Pack of 12.
