A fascinating timer that has a quirky flow of liquid beads through two spinning wheels. The density of the transparent base liquid is less than the neon-coloured drops, making for the interesting flow. Not only a lovely visual display, this entrancing timer demonstrates the mechanics of un-mixable liquids of different densities. A calming addition to the classroom, or great as a desk distraction at home or in the office.

What you get
Double Neon Wheel Liquid Timer with blue gel in a box. Timer measures 5 (L) x 4 (W) x 12 (H) cm.
How does it work
Simply turn the timer over and watch the neon-blue liquid spin the paddle wheels drop by drop and fill the chamber below. Flip it over and the blue gel drops spin the paddle wheels in the reverse direction. The colour liquid drips are heavier (more dense) than their transparent liquid surrounds, thus easily sink to the bottom creating a peaceful visual show as they do.
