The ''Sand Clock'' is really called an Hourglass, and the reason for that is because it takes the sand and hour to reach the other end of the glass. An hourglass is a curved shaped object that has two ends. The hourglass Has sand inside it which Is placed at the bottom of the hourglass, but when you turn the hourglass up side down, the sand slowly runs through a hole to the other end of the glass. When the sand has finally finished flowing it will end up looking like how it was in the first place.
An hour's worth.
Hourglass
Sand + glass = hourglass, hourglass + life = time. <3
The number of grains of sand in an hourglass can vary depending on its size and design. However, a typical hourglass may contain around 10,000 to 15,000 grains of sand.
An hourglass measures time with grains of sand. The sand trickles from the top chamber to the bottom chamber, indicating the passage of time as it runs out.
