Galileo Thermometer

The Galileo Thermometer is a super cool and stylish way to check the temperature—perfect for any science lover. It’s a sealed glass tube filled with clear liquid and colorful glass bulbs that each have a different density. As the temperature changes, the bulbs rise or sink, showing you the current temp. To read it, just look at the metal tags hanging from the bulbs. If one is floating in the middle, that’s your temperature. If there’s a gap with bulbs at the top and bottom, the temp is somewhere between those two tags.
