Sometimes two chopsticks are placed parallel on top of the glass of beer, and the shot glass is carefully balanced between them. The drinker slams the table with their fists, causing the sake to fall into the beer. It should be drunk immediately, and works best with warm sake.
Alternatively, the drinker may count to three in Japanese, "ichi...ni...san...SAKE BOMB!" Or they may simply yell "KANPAI!"
A variation of the sake bomb is to "bomb" a shot of warm sake into chilled Red Bull energy drink.
