The Peristaltic Shot - a mechanical precision shot pouring device

This device comprises a mechanically driven peristaltic pump which pulls liquor from a bottle into a graduated separatory funnel serving as a measuring device, after which a precisely measured shot can be deposited into a glass. The pump body consists of five cantilevered arms bearing rollers which compress a soft silicone tube. As the rollers travel clockwise around the housing, they create vacuum inside the tube and draw liquid up from the bottle. A handcrank below the pump housing is limited to clockwise turning with a one-way bearing hidden inside the stem.

We're gonna need a bigger shot glass....

But a shot glass is its own measuring device, and it didn't even fill that one up!? That's not right at all!
