Animal Superpowers
Every one of these is real. Pick a superpower, find out how it works, then try the mini-experiment yourself.
Dog: A nose that reads the past
A dog's nose can tell who walked down the street hours ago.
A dog breathes in and out at the same time, so scent keeps flowing over the smell sensors without a break. Each nostril samples separately, which lets a dog work out which direction a smell came from.
🔬 How faint can you go?
Slide the scent down to almost nothing. See where your nose gives up — and where a dog carries on.
Trained dogs can detect some scents diluted to one part in a trillion — like one drop in twenty Olympic pools.
