A 3 minute bomb timer
This is a 3-minute bomb-style countdown, pre-set and ready to go — a full game round. Hit Light the Fuse and the big digital readout starts falling from 3:00. The stage pulses red, the warning symbols flash, and the ticks speed up as the fuse burns down. The last ten seconds shake the screen, and at zero you get a flash-of-light BOOM. Nothing to install and nothing to sign up for.
What a 3 minute fuse is good for
3 minutes is the right length for board-game turns, debate rebuttals and three-minute drills. If you need a different fuse, every other length is one tap away below, or type your own into the box.
How to use it
- Press "Light the Fuse" - or click the digits, or press Space
- Go fullscreen - the ⛶ button or F, which is where the drama actually lands
- Mute if you need to - the 🔊 button silences the ticks and the explosion
- Defuse early - Reset stops it dead
What happens as the 3 minutes run down
- Early on - slow pulse, soft ticks, calm red glow
- Halfway - faster pulse, higher-pitched ticks, warnings flashing harder
- Final 10 seconds - the stage shakes and the ticks go rapid
- Zero - white-yellow-orange explosion, BOOM, alarm, then back to defused
Using it in a classroom
A bomb timer makes a 3-minute activity feel high-stakes without being genuinely stressful — the countdown does the work that nagging otherwise would. Project it on the board, mute the ticks if the room is already loud, and let the visual pulse carry the urgency. It works well for tidy-up races, timed group work and "finish before it blows" challenges.
