Video Introduction

Are cats solid or liquid?

This is an unsolved mystery that has plagued mankind for centuries.

When you put cats in any container, they will fit perfectly. There can be a box of cats, a bowl of cats, or even a cup of cats. Fardin, a French scholar, once proved that cats are mysterious substances with solid-liquid duality through the Deborah number in rheology, and won the 2017 Ig Nobel Prize in Physics. [1]
