Choose your bomb
Every bomb runs a 2-minute transition countdown. Pick a preset or set your own time. Three bombs are free to play, one more goes free each day, and the whole crew is ready whenever you want them.
Smoother classroom transitions
Transitions add up fast, and a visible countdown helps. In one classroom study (Ardoin et al., 2015), on-screen transition timers cut transition time by 67% and gave teachers back about 39 minutes of instruction a week. Put the transition timer on the board, give a two-minute warning to switch activities, and let the class race the fuse.
Two minutes fits most quick moves: packing up, switching stations, lining up at the door. Use 3 to 5 minutes for bigger transitions, or tap Custom for any length.
