Hourglass

Before clocks, some people kept time by putting sand into glass containers that had a small connection between the top and bottom. It took a certain amount of time for sand from the top part of the glass to fall into the bottom--usually, one hour (hence the name). When all the sand was in the bottom chamber, a person would flip the hourglass to calculate the next hour and measure the amount of time passed.
