5 Minute Water and Sand Hourglass Timer w/Green Liquid
5 Minute Sand and Water Hourglass Timer
An interesting twist on the typical sand timer, this particular hourglass features both liquid and sand. The hourglass is suspended in a glass cylinder that has been filled with a green water, and a small hourglass is suspended within the liquid. As the cylinder is flipped, the sand timer begins to not only rise back up to the top, but to pass sand from the upper bulb to the lower. There is enough sand contained within the hourglass for a full five minutes to elapse.
It has an overall height of 9.25" and a diameter of 1.8".
