The Czech Republic has miraculously one-upped NYU’s Going Green obsession by bringing conservation to their plumbing systems. With two toilet-flushing options available in most Czech bathrooms, occupants have the option to match virtually every WC visit with an appropriate flush. Resort back to the childish code words defining what it means to go #1 or go #2 and apply similar logic to the small and large button flush system. Simply put, the small button exerts less water than its larger counterpart, thus avoiding any need for the awkward double flush.

For those of you who conducted your own unscientific experiment by standing in the WC for a few minutes to compare the reaction of each press of the button, we applaud your curiosity. For those who wrote the double button system off as a strange foreign quirk, take note and try to only use as much water as necessary. The polar bears will thank you.
