Visual Timer

Bomb Timer

Share a timer: add ?t= and the number of seconds to the address, e.g. visualtimer.org/?t=420 for 7 minutes.

The fuse burns shorter every second, and when it reaches the bomb — BOOM! Kids love racing to finish before it goes off, which makes it a favorite for clean-up, quick challenges and classroom games.

Set any time from a few seconds to an hour. Turn the sound on for a chime at the end, and go full screen to show it on the board.

Frequently asked questions

Is the bomb timer scary for young kids?

It’s a friendly cartoon — no loud explosion sound, just a chime and a "BOOM!" on screen. For very young children, the pie or sand timer may be calmer.

Can I set a 10 minute bomb timer?

Yes. Tap 10 min (or type any time) and press Start.
