Heavy Water Ice Cubes

So apparently there is this fluke that occurs on occassion in Hydrogen atoms which makes it have a neutron. Now, Hydrogen standardly only has one electron and one proton, yielding a very light molecule. But when a hydrogen atom is formed having a quite heavy neutron in it as well you can end up with a substance called "heavy water" (deuterium) simply because it weighs more than regular water.This water ends up being 10% heavier than normal water, making it sink, even when made into ice cubes. So this yields some pretty neat looking effects, having ice sunk in your glass.

The primary use for heavy water is in nuclear reactors, though it is safe to handle (not being radioactive itself) it's not recommended for drinking purposes. So while it's neat to toss in a glass of water don't drink it afterwards. (though it's only dangerous in high quantities, having strange effects on the body's biochemical processes)
