Overview
Galileo Thermometer with 5 Coloured Balls Height 18 cm Borosilicate Glass Metal Tags Glass Decoration for Desk and Shelf

The Galileo thermometer with 5 coloured balls is a compact glass ornament that also indicates the temperature in the room. The cylinder, standing at 18 cm, is made of borosilicate glass and is filled with a clear liquid in which the glass balls float freely. Each ball has a metal tag hanging from it, indicating the temperature in degrees Celsius. Each of the five balls corresponds to a different temperature value, allowing you to monitor changes in the room continuously. The thermometer is suitable for a desk, a library, a dresser, or a child's room for older schoolchildren.

The principle of the thermometer is based on the discovery by physicist Galileo Galilei that the density of a liquid changes with temperature. When the liquid warms up, it becomes less dense and the balls sink one by one; when it cools down, they rise back to the surface. You can read the temperature from the lowest ball of the upper group. The entire cylinder stands on a glass base, requires no batteries or power supply, and operates completely silently. The coloured balls with shiny tags create a small artistic installation and attract the attention of visitors.

The balls are made of glass, and each contains liquid of a different colour, making it easy to distinguish the individual temperature values even from a distance. The metal tags with numerical values hang below the balls and are clearly readable through the transparent cylinder. The thermometer also serves as a visual aid, allowing you to explain the relationship between temperature and liquid density to students or schoolchildren. The small base fits even on a narrow shelf.

For the most accurate reading, place the thermometer away from direct sunlight, heating, and drafts. When all the balls are floating at the surface, the temperature is lower than the lowest value on the tags. When all are resting at the bottom, it is higher than the highest value. The surface of the glass can be wiped with a soft dry or slightly damp cloth. As this is a glass product, position it to prevent it from falling off the table.

The Galileo thermometer with 5 balls combines the function of a simple room thermometer with a decorative appearance. Its small height makes it an ornament that fits almost anywhere. The coloured balls in the glass cylinder captivate both adults and older children interested in physics. It is a suitable gift for birthdays, Christmas, or as a corporate gift. You can read the temperature at a glance without batteries and without adjustments.
