ID Code: I1-19
Purpose: Demonstrate differential thermal expansion between two liquids, and to take us all back to the 1960s.
Description: Globs of petrolium-based fluids expand at a different rate from the water bath in which they are placed. After the mixture gets up to its equilibrium temperature differential expansion occurs, leading to the rising and falling of the globs as they become more or less dense than the liquid bath. It's also kind of pretty.
