30 Minute Bomb Timer

A thirty-minute bomb timer frames a longer challenge — a project, a big tidy, a sustained team game — with a slow-burning fuse that keeps a distractible class aware, in a fun way, that the clock is ticking.

About the 30 Minute Bomb Timer

Thirty minutes on a burning fuse keeps a long task from dragging — the slowly shrinking fuse is a constant, playful reminder that the clock is running.

Frequently Asked Questions

Does the 30 minute bomb timer keep accurate time in the background?

Yes. It counts down against the real clock rather than ticking in the tab, so your 30 minute bomb timer stays accurate even if you switch tabs or lock your screen — and the alarm still sounds at zero.

Can I change the duration, or switch away from the bomb clockface?

This page opens preset to 30 minutes on the Bomb clockface, but you can set any duration and switch to a different clockface at any time using the controls below the timer.
