Experiments unfortunately do not have a straightforward path (see: CERN), since not everything can be predicted.

We are density matching our food colored glycerin today. The scale that we use is sensitive up to 4 past the decimal. We can basically watch water evaporate, which is surprisingly really cool (or I’m not surprisingly nerdy).

Density matching means we are desperately trying to get one color’s density to match the other. It’s surprisingly not as trivial as it sounds. The densities must be very exact, or else, the one will sink or float.
