These adhesive Liquid Crystal circle stickers change colour in response to temperature. When not in use, the stress circle will stay black. If you’re relaxed, your skin will be warm; and the circle will turn blue. If you’re tense, your hand will be cold; the circle will stay black.

In addition to keep your stress in check, this product is an ideal learning and educational resource.

The circle will not change colour below 21°C. To find out if it is you or the stress circle, hold your hand on your back, just below the neck. If your hand feels cold, it's probably you. Otherwise, run the circle under hot water or hold it up to a heat source like a light bulb. If it changes colour, the circle is working.

When this product is shipped in winter or to especially cold climates, the Liquid Crystal can go into suspended animation. Revive it by placing near a radiator or another mild heat source.
