Rather than slap together a bunch of plumbing parts I decided to make them look more like "product" to up the ante. All it took was some time at the PC and a little printer ink to make some labels and staple them to some zip lock baggies.
The video shows the pocket catapult.

The catapults cost almost nothing to make and it took me maybe an hour to make 24 of them. The marshmallow shooters ended up costing about $2.50 in parts each. When I dropped them off to the ladies at the sale I suggested $10 for the Shmooters and $2 for the Pocket Catapults, but they felt they could get $3 for the catapults. Hope they Sell:)
Please note I am not selling these or advertising goods for sale; I made these for a BSA fund raising event and I am sharing this idea, not hawking wares.
