i had two tubs, water in one, and a bunch of small tools (mini droppers, spoons, pvc pipe, straws, ladles, etc.).  the challenge was to move the water from one tub to the next without picking up the tub or getting any other tools.

by the way, the oily film you see on the water is from an organic mint extract i used (thinking it would just add a nice smell…i won’t use it again).
