Choose your bomb
Any bomb you pick runs for 8 minutes. Three bombs are free to play, one more goes free each day, and the whole crew is ready whenever you want them.
Other timer lengths
Eight minutes is the short station. This free 8 minute bomb timer fits center rotations for younger grades, writing warm-ups, partner projects, and the deep-but-not-too-deep cleanup that one shared playroom always needs.
For rotations, eight minutes hits a sweet spot: enough time for real work at each station, short enough to fit four rotations in a typical block with transitions to spare. Tap Run it again between groups and the next crew is on the clock.
Need a rounder number? The 10 minute bomb timer is the classic, and the 5 minute version handles quicker resets. Custom covers any length up to an hour.
