Hourglass
An hourglass is a fun way to measure time. It uses sand that flows from one glass bulb to another.
Appearance
The Hourglass is a time-measuring device with two clear glass bulbs connected by a narrow neck, creating a distinctive figure-eight shape. Fine, often white or yellow sand slowly flows from the upper bulb to the lower, marking the passage of time. It's usually encased in a wooden or metal frame.
