Two Owls
Watch
Episode 1: How high can they jump? 35 animals walk past the owls' tree and try to jump. Guess first, then count how many of their own bodies fit under the jump.
For grown-ups
Each animal gets about 20 seconds: it walks in, says hello, jumps, and then we stack copies of the animal to measure the jump in body lengths. Small animals turn out to be the best jumpers for their size. Every number is listed on the sources page.
