This YouTube video will show you an unbelievable art form. Bill Dan is an artist specializing in rock balancing. It’s an art form that seems to defy physics.

Dan stacks rocks of different shapes and sizes. That sounds unremarkable, until you see the end result. His towers of rock look impossible. Large rocks are balanced on end on top of mere pebbles.

There are no tricks here. He’s really balancing the rocks in these formations. His towers are actually pretty stable. See 1:30 for proof. That’s just amazing.
