Agar cubes: what affects diffusion sim

Cut pink agar cubes with a scalpel, pour hydrochloric acid into a beaker in a water bath, set the temperature and the acid concentration, and drop the cubes in. Each cube clears from the outside in while a stopwatch runs. A results table fills with side, SA, V, SA:V, time to clear and rate 1/t, and your own readings are plotted on a graph.
