Surface Tension (itch) (pbl)

The Head
A circular room with a pool of black liquid at its centre.
Emerging from the liquid is a large set of scales, on one side of which sits a large heavy-looking weight semi-submerged in the liquid. Where the weight meets the liquid the word "TDIITLI" can be made out in laser-engraved letters.
The other side of the scales is empty.
