A Rainbow That Lasts Half an Hour

For longer activities like art projects, science experiments or group presentations, a thirty-minute rainbow keeps everyone aware of time without constant reminders. Each band represents a clear slice of the session.

Teachers can say "we will clean up when the blue band is gone", and parents can use it for play-date limits or longer screen sessions. The digital time is shown too, for the grown-ups.

Frequently Asked Questions

How can I use a 30 minute rainbow timer in class?

Use it for art and craft projects, lab activities, group presentations or test sections. Refer to specific colours to give students mid-session checkpoints.

Can I pause the rainbow timer?

Yes. Press Pause or the Spacebar to freeze the rainbow, then resume when you are ready.

Why do rainbow timers work so well for young children?

Kids who cannot read a clock yet can still understand "when the colours are gone, we are done". Shrinking colour bands turn abstract minutes into something they can see and talk about.

Can I use the rainbow timer on an interactive whiteboard?

Yes. It runs in any modern browser and has a one-click fullscreen mode, so it scales cleanly on smartboards, projectors and tablets.
