Morskoiboy created an hydraulic typewriter that mixes cocktails — the typewriter keys inject different liquids into a big LCD-like display, which then decants them into a waiting beaker.
So, if you're interested, let me explain this contraption and the mechanism that makes it work. At the top of the machine there is a slot into which a bottle with alcohol, water, or even milk can be screwed. The essence of the art here lies in the ability of the syrups or liqueurs to tint the neutral color of the liquid. In the picture below you can see the connector itself and the regulator (which is actually an IV Rate Flow Regulator I picked up in a drugstore), which opens or closes off the air flow into the bottle and thus acts as an on/off switch. Once it enters the machine, the liquid spreads across the fourteen tubules.
