The Sensory Sensations Twirly Wheeled Timer is an entertaining and fun gadget for young and old that also demonstrates basic scientific principles.

Each timer contains coloured fluids of different densities. To create the drop like blobs, the liquids inside the timer must be immiscible or mutually insoluble.

This means that the coloured liquid won't mix with or dissolve into the clear liquid. Because they don't mix we can observe gravity at work with the heavier coloured liquid always flowing to the bottom of the timer.

The Twirly Wheeled Timer may also aid concentration. The visual stimulation of the predictable, rythmic and flowing motion of the Twirly Wheeled Timer provides a subtle and engaging opportunity to refine visual tracking skills, with the spinning wheels adding to the appeal.
