■ An interior set featuring a storm glass and a glass float thermometer.
The Glass Float Thermometer where glass spheres float or sink according to the temperature, and the Storm Glass where the crystal shape changes depending on weather conditions.
You can enjoy these two popular items from _Fun Science_ together.

＜What is a Galileo Thermometer?＞
This thermometer is made using the principle discovered by physicist Galileo Galilei that the specific gravity of a liquid changes with temperature.
The rising and falling glass spheres indicate the temperature, and the actual temperature is read from the lowest numbered plate of the floating glass spheres.

＜What is a Storm Glass?＞
A Storm Glass (weather predictor) used as a weather forecasting tool during voyages in Europe in the early 19th century.
It is said that the state of crystals within the liquid changes depending on the weather and temperature, allowing you to enjoy the unique changes in the crystals.
Storm glasses are made by dissolving multiple chemicals in alcohol and sealing them in a glass container.
Due to detailed research on this device by British Navy Admiral Robert FitzRoy, it is also known as FitzRoy's barometer.
While the relationship between weather conditions and crystallization within the liquid has not been scientifically explained, and it cannot be used for accurate weather prediction,
the liquid and crystals change uniquely in response to surrounding environmental changes, so please enjoy it as a decorative interior piece.
