Here's an experiment that you could try at home:

Takes 2 cups of water of equal volume, one hot and one cold. Put a single drop of food coloring into each cup and time how long it takes for the color to fully disperse throughout the water.

Record your units in SI units like cm or mm, because inches are stupid and scientists have agreed to not like them. You are a scientist now, so you must join the club.

Submit your findings to the journal of Lemmy for peer review. Extrapolate into other forms of measurement if you want.

If you want it to be even better, measure 3 temperatures (in °C, mind you): room temp, hot, and cold. Then you can plot them on a curve of distance vs time.
