Description
The Sensory Sensations Crossover Timer is an entertaining and fun gadget for young and old. 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 other coloured liquid or the clear liquid. Because they don't mix we can observe gravity at work with the two heavier coloured liquids always flowing to the bottom of the timer.
The Crossover Timer is also a great tool to help with concentration. People who enjoy visual stimulation seem to respond well to the predictable, rythmic and flowing motion of the Crossover Timer.
It provides a subtle, engaging opportunity to refine visual tracking skills. Timers can also assist with anxiety levels and help with calming.
