They were testing the phrase “knock your socks off” and because its the mythbusters build team (which consists of 3 boom addicted gremlins) they decided to go to a quarry near Esparto california to test the myth by blowing shit up. This time they got 500 pounds of ANFO. The detonation was pretty damn big.
They started getting phone calls, turns out they and the experts underestimated the size of the kaboom, reports of broken windows, car alarms going off, people getting knocked out of their seats, hell one news station reported that they leveled the town.
According to grant, that’s why they can no longer go back to esparto.
