In this Squiz Kids Science Short, we explore what smell actually is, how your brain recognises different scents using patterns of signals, and why smell has been one of the most mysterious senses for scientists to understand.

It’s a fascinating look at one of your body’s most powerful — and surprising — senses… hiding right under your nose.
