Liquid Sand Timer "Contra Mini"

An amazing sand timer: because the sand, which normally falls down, does not do this at all. Only when you invert the sand timer does it begin to move, but in an upward direction!

How is that even possible? The density of the "sand" pellets is lower than that of the surrounding liquid. The specific weight of this artificial sand is lower than the liquid.

This beautifully designed sand timer is made of highly transparent acrylic plastic, filled with water and yellow or red granules.

The sand timer runs for approx. 1 minute.
