Have you tried to go back to the present yet? No dice? Hmm. Your potential organic matter is too dirty. Tried to wash it? Ouch. Good thing there's a decent supply available.

There is a reason that the water cooler's pressure is so high in the past and so low in the present. It's a little something called YOU. See what you have on hand to correct the problem. :)
