Galileo Tube Thermometer

At first glance, the operation of this thermometer may seem intricate, but it’s surprisingly straightforward!

The external temperature influences the liquid-filled bottles inside, so here’s a helpful tip: avoid placing the thermometer too close to a heat source to ensure precise readings.

These bottles contain a unique liquid that reacts to changes in the surrounding air temperature. When the temperature increases, the bottles with lower-temperature indicators will sink, while those with higher-temperature indicators will rise. The bottle indicating the exact temperature will rest in the middle.

This thermometer not only functions as a scientific instrument but also serves as a decorative piece, seamlessly blending both form and function.
