During the 1950’s outside of Las Vegas, the military had test sites for conducting the atomic bomb. Hotels and resorts in Las Vegas were arranging picnics where guests could watch the explosions in the distance. At the same time, the new Atomic cocktail had an exploding effect after having one or two of them!
