School Project: Thermometor
For school, I made a simple thermometor. We took clay, a bottle, a straw, equal parts rubbing alchol and water, and food coloring and made it. It is just amazing how it works. And when we left it in the sun, the water mixture traveled up the straw, even without us putting our hands on the bottle!
