30 Minute Hourglass
The hourglass, also known as a sandglass, sand timer or sand clock, has been used since time immemorial. They were very popular on board ships, as they were the most dependable measurement of time while at sea. Unlike other early methods for measuring the passage of time, the motion of the ship while sailing did not affect the hourglass.
