How can I build a termometer using coke instead of mercury?

Question

I was hoping to see if there is a way to do the termometer in the thoerical way only, cause I don´t have the time to try to do it in the experimental way

Answer 1

Two bottles of coke, approx 5 feet of small plastic hose, two corks to plug the bottles with the two ends of hose attached to it. Before the assembly, fill the hose with small amount of coke. Position the two bottles in the same level with the hose hanging in U shape. The levels of liquids on both ends of hose should be the same. Each bottle should have exactly the same amount of coke. Now you can relate the difference of temperature between two bottles by looking at the difference of height of liquid on hose's ends.

Just figure out the scale yourself ;=)

Answer 2

All liquids expand on heating. It only takes a tube long enough to see the difference and calibrating it. One of the first thermometers was made with water, which is the major ingredient in Coke, and was 12 feet long.

Answer 3

You would have to make a low expansion glass tube proportioned to the expansion of sugar water instead of mercury or alcohol (red fluid in some thermometers) and the easiest way to make it would be a large base bulb with a slender tube rising above it, but it would have a lot of mass and be very slow to react to temperature.

Answer 4

Ive never even heard of that. Im intrested to see these answers.
