Sand Timer Set of 6

A sand timer, also known as an hourglass, is a device used to measure a certain amount of time.

It consists of two glass bulbs connected by a narrow neck and filled with fine sand. When the bulb containing the sand is flipped over, the sand flows from the top bulb to the bottom bulb through the narrow neck.

The sand takes a specific amount of time to completely flow from one bulb to the other, which is determined by the size and quantity of sand. Once all the sand has flowed, the timer can be flipped again to measure another period of time.

Sand timers are often used for timing activities or games, as well as for decorative purposes.
