Comeback idea

A small line of wearable and fixed indicator badges that show ozone levels for pool, lab and home air-quality checks.

The write-up

OzoneWatch turns air quality into something you can read at a glance, and it's ready for a second act. Plenty of people now want to know what is in the air they breathe, and a simple colour-changing badge makes that check quick and easy for homes, schools and workplaces. The name is up for a fresh start, and here's how you'd relaunch it: a compact range of colour-change ozone indicator badges sold in multi-pack refills, ordered from ozonewatchshop.com.
