Using yellow liquid to flush toilets [Improbable Research]

Improbable Research, as the site says, is research that makes people laugh and then think. "Our goal is to make people laugh, then make them think. We also hope to spur people's curiosity, and to raise the question: How do you decide what's important and what's not, and what's real and what's not — in science and everywhere else?"
