Inspired by the YouTube channels "Will It Crush?" and Blendtec’s "Will It Blend?", Grant Thompson is here to ask the next big question: “Will it flush?” He enlisted the help of Cody’s Lab (the guys who flushed mercury down a toilet) to see what happens if you try to flush a block of sodium down the toilet.

Sodium metal is near-white in color and flexible, so it’s perhaps not what you’d expect when you think of a metal. Nevertheless, it’s one of the most reactive metals in the periodic table after potassium, caesium, francium, and rubidium. Like all of these alkali metals, it creates a pretty violent exothermic reaction when added to water. In other words, an explosive heat-producing bang.


Remember, don't try this at home – calling a plumber at short notice can cost a ton.
