Cats fill./ Cats spill./ Cats flow downhill.// Cats tip./ Cats drip./ Cats grip, snip, rip.// Cats are a liquid/ Except when they’re not.

Inspired by an Ig Nobel Prize–winning investigation of how cats behave like liquids, this book introduces some of the physical properties of liquids―they adapt to fit a container, they flow like fluids―and is just pure fun.

Like its inspiration, it makes you laugh, then think. Back matter includes a brief introduction to the different physical states: solid, liquid, gas.
