Measure time and learn more about relative density with this intriguing liquid timer. Shaped similar to a traditional sand hourglass, this timer features colourful granules which rise to the top rather than dropping to the bottom to represent time passed.

The new jumbo version of our popular mini reverse timer, this maxi timer certainly produces some interesting and intriguing anti-gravity effects as it counts upwards.

Whether you need a 2 minute timer or simply enjoy a unique liquid transfer display in action, this vibrant timer is mesmerizing to watch and fun to flip over, again and again.

What You Get

Maxi Reverse Timer. Features a two minute, transparent hourglass shaped timer containing a clear liquid and coloured granules. Available in a variety of vibrant colours. A random colour will be selected for your order.

How Does it Work?

Maxi Reverse Timer demonstrates the effect of relative density and buoyancy - simply allow the timer to settle, then flip it over to observe the coloured granules rise through the narrow neck up to the top bulb. This rise in the coloured granules is possible because they are less dense, or lighter, than the clear liquid they're suspended in. The result: a captivating anti-gravity display.


  • Relative Density
  • Buoyancy

WARNING: CHOKING HAZARD - Small Parts. Not for children under 3 years.
