So I had to go to the local Lowes to get parts to fix some broken pipes and you know you are a bit messed up when you see everything for its bdsm value do here goes.

Pythagoras cup, greedy cup or self starting siphon. I took one look at this and the first thing I thought was hmm.... if only I could put a drip bottle over this to a breathing tube so that it could occasionally dispense nasty fluids or just coca cola when the cup is filled enough to activate.

2 vertical pipes connected by two 45 degree bends with a dripping bottle on one side and a heavy plastic bobber with a string with the key attached on the other end. When oriented vertically the dripping bottle fils the tube and slowly lifts the bobber up which lowers the key on a string to you.
