Hydrodisplacer

The Hydrodisplacer can move water from a deeply soaked pool and into an empty pool, thus making it a lot easier to reach higher places. The volume of water that can be contained by a Hydro-Displacer is far greater than it's external volume would seem to indicate. It can drain several thousand gallons of water with no notable increase in weight.

It is found in the Blarg Station on Nebula G34
