Description: This hourglass is truly incredible. At first, the liquid inside drifts down around the hourglass, drop after drop, as if it was moving on invisible stairs. But that is not all. If you turn it up side down the drops will start going up again, making the waterwheel move. You simply have to see this. You will never get bored by this gadget and it will surely rivet your attention for hours.

Idea: For those who urgently need to change something in their everyday routine.
