If you ever played videogames you’re probably familiar with the charismatic Vault Dweller, the mascot of the Fallout series videogames. But why is it that the little guy is bringing his thumb up? Turns out it’s not just the much needed positive attitude. He’s actually measuring the distance of a nuclear explosion. It seem that an old nuclear war survival tip said that if with your arm extended you could cover the mushroom cloud of a nuclear explosion with your thumb then you were far enough to survive. I think that wind direction will play a big role as well but still, fun to know and I hope I NEVER have to try it out for real!
