The Flush Tracker Does Exactly What You'd Expect
It tracks how flushes travel through our sewers, and it's more engaging than you might imagine.
The Flushtracker: You give it an address (it currently only works in a few locations) and it tracks the path of a flush from that location, from toilet to sewer to its final destination at a treatment facility or out in the open ocean.

World Toilet Day, by the way, is November 19.
