This video drives home the importance of social distancing. It shows 500 mouse traps placed next to each other, and each one has a ping-pong ball on the trigger. When one ping-pong ball is dropped onto a trap, it sets off a wave of bouncing balls and snapping traps that are flying everywhere. Then they do a second version where the traps are placed further away from each other, and this time the ping-pong ball goes bouncing past without setting off a chain reaction.
