What do you know today that you didn't know yesterday?

During wwii the US developed a bat bomb to drop on Japan.    The bomb contained dozens of live bats each with a tiny clockwork incendiary device strapped to its body.   Before flight the bats are chilled to make them sleepy.     they are loaded into the bomb in the drowsy state.   During the bomber’s flight to Japan the cold of high altitude would keep them sleepy.    Once the bomb is released the spring loaded casing would snap open, sprinkling drowsy bats over Japan.    The theory is as the bats fall into lower warmer air, they will wake up and seek to roost inside the attic of flammable wood and paper traditional Japanese houses, where their attached incendiary devices will spring to life and burn down the houses.

During tests it was found the very fast passage of free falling cold bats through warmer air wasn’t sufficiently lengthy to warm the bats.   Instead of reviving and resuming normal bat flight during decent, they plunge like frozen chickens to the ground, not helped by the weight of their attached parasitic pyrotechnic devices.

Several test drops were conducted in California,  then the program was quietly shelved.
