To the uninformed eye, Maru the cat might look like a solid, with characteristic structural rigidity. His shape seems stable, resistant to change.
But, under closer observation, and with the help of a small cardboard box, we've discovered something very, very cool: cats are 100 percent liquid.
Liquids change shape to fit their container, and Maru is shown to be capable of just that when he climbs into any number of boxes.
The majesty of science is overwhelming.
