Pneumatic Cash Machine

We don’t charge for events but we will gladly accept donations. In fact, we built a pneumatic cash machine for that purpose. With the flick of a switch, a hidden vacuum is activated: you can watch your dollar bills swiftly sucked up through overhead plastic piping and deposited in a conical holding chamber. You can see the pneumatic cash machine’s parts and stages of construction below.

Watch it in action!
