What Happens When You Drink Heavy Water

Water itself is a fascinating substance. Deuterium oxide, water's slightly overweight chemical brother, is even more interesting. Unlike regular dihydrogen monoxide, deuterium oxide contains hydrogen with a mass of 2, meaning that a neutron has joined in with the proton. This makes the deuterium oxide 10 percent heavier than regular water. When frozen, it sinks rather than floats like a typical ice cube.

Cody from Cody's Lab decided to subject himself to some heavy water testing. He likened the taste to the sweetness of hay or grass (which we'll take his word for).

Too much heavy water can be toxic, as it slows down the body's chemical reactions. However, Cody didn't drink nearly enough to do significant damage.
