⏳🪨 A sandglass is a timekeeping device consisting of two glass bulbs connected by a narrow neck, with sand flowing from the upper bulb to the lower one. It symbolizes the passage of time, as the sand gradually moves from one bulb to the other, measuring a specific duration. The hourglass shape of the sandglass and the steady flow of sand represent the ephemeral nature of time and serve as a reminder to cherish each passing moment.
