NASA scientist Mark Rober gets into the physics of rock skipping, and because he’s Mark Rober, he also build a rock-skipping robot!

Poetically known as Baikal Zen Rocks, this rare effect happens when a flat rock that has fallen onto the ice catches the spring sun and melts the ice underneath it. Only a thin pedestal supporting the rock remains. The pedestal is far enough from the sides of the rock that it escapes melting. At night, the water beneath the rock refreezes.

Can you GROW an Opal?

By growing silica nanoparticles of the right size, synthetic opal can be grown. How realistic it looks is another question, though.
