Defying Gravity (E01)

In Africa, a caracal's 'rocket-propelled' launch enables it to catch birds in flight. In the Australian outback, a kangaroo's hop is key to finding water in a desert of over a million square kilometres. On an English farm, an insect's ultimate ejector seat accelerates it to 700G with help from a clutch in its crotch. And high above the jungles of Borneo, a leaping snake's unique shape allows it to glide, even without wings. (BBC)
