Beautiful Heavy Ice

Searching for pictures for my series about Fusion Fuels, this beautiful photograph came to my attention.

Heavy-water ice cubes sink in ordinary water (left). - deuterium - heavy water

Here is the source.  They don't explain (as far as I can see) what is happening here.   Both glasses contain cold water, and the glass on the right has an ordinary ice cube floating in it, just as you would expect.

But the ice cube in the left glass is frozen 'heavy water' - deuterium oxide.  As you can see, it is heavy.

Just WOW!

p.s.  If I'm right, that was an expensive photograph!
