Dude!!!! Ive made loads of these way easy and I think way cheaper. Ya know the little yoplay yogart cups? Just cut the backs off of them. Get a plastic bag and cut a circle out of it. Then cut a rubber band so it is like a rubber string. Then stick the middle of the rubber band in the middle of the bag circle. Pinch the band and the bag as to make a handle. Tape around the handle pinch. Knot the ends of the band and tape them to the edge of the cup's mouth opening. Pull the handle through the mouth and tape the edges of the circle up over the hole you cut. When you pull the handle and let go, it shoots a ball of air.

But you pull something back.
Though, I bought a real store bought one in Montreal.
I'm going to make this with a small container right now.
