Two historical devices in one.
The storm glass was once used by seafarers to predict oncoming storms, the storm glass barometer came into general use in the early 1700s, and responds to atmospheric fluctuations to forecast the weather.
In 1593, Galileo discovered that the density of liquids reacts predictably to changes in temperature. He invented a device that allowed temperature variations to be measured.
