Dirt Napper
Getting Warm
Thermoscope invented by Galileo Galilei in the early 1600s.
A brief on the science behind it:
Archimedes’ Principle: Objects float or sink depending on whether they are less or denser than the fluid they’re in.
Liquid Density: The clear liquid inside the thermoscope expands slightly as it warms, making it less dense. When it cools, it contracts and becomes denser.
Calibrated Bulbs: Each colored glass bulb has a small metal tag with a specific weight. These weights are carefully chosen so that at certain temperatures, the buoyant force matches the bulb’s weight.
