Synchronicity Island Purifies Water Using the Power of You

If we’re going to be enslaved, we might as well have a symbiotic relationship with our slave master. The Synchronicity IslandĀ allows us to buff up our beautiful, if slightly flabby, bods while our cardio workout provides all of the power needed to purify water. Metaphorically turning water into wine, except the wine is actually more water.
Powered by a series of exercise machines, the Island uses our kinetic energy to pump water into four tanks, which starts the purification process. We are the bearers of clean things and we have the shaky legs to prove it.
