Choose your bomb
Any bomb you pick runs for 15 seconds. Three bombs are free forever, and nine more are ready whenever you want the whole crew.
Other timer lengths
Fifteen seconds is the sweet spot for taking turns. This free 15 second bomb timer keeps a card game, a board game, or a circle-time game moving without pushing anyone into a silly move. One player, one fuse, one turn, and then it is the next person's problem.
It is the right length for partner swaps too: fifteen seconds to talk, then change over, then change back. Think-pair-share, buddy reading, and roll-and-retell all run on that rhythm, and a burning fuse says "swap now" far better than a grown-up counting down does. For a secret length that could go off at any moment, try Pass the Bomb.
Away from school it makes a tidy decision timer, the sort that settles an argument about which film to watch before it properly starts. Want a slightly longer turn? The 30 second bomb timer is the next rung up the ladder.
