A 5 minute bomb timer
This is a 5-minute bomb-style countdown, pre-set and ready to go — a classic five-minute fuse. Hit Light the Fuse and the big digital readout starts falling from 5:00. 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.
What fits in 5 minutes
Five minutes is the default for a reason — a classroom warm-up, a group brainstorm, a station rotation, or the last push of an escape room all fit comfortably.
It suits classroom activities, escape-room finales and team challenges. If you need a different fuse, every other length is one tap away below, or type your own into the box.
How a 5 minute fuse feels
The middle minute is where a five-minute fuse earns its keep: long enough to forget the timer, short enough that the acceleration lands as a surprise.
Before you start
The ⛶ button fills the screen, which is where the effect actually lands, and 🔊 silences the ticks and the explosion if the room is already loud. Reset defuses it early. There is a fuller rundown of the stages, the sounds and the classroom uses on the main bomb timer page.
