Students discovered that Epsom salt or magnesium sulfate dissolves much better and in higher concentrations than in cold water.
This simulated the minerals deposited at vents where there are weaknesses in the earth's crust. Especially - the ocean!
Then, waste not want not, the students added a little food coloring for another round of making some crystals.
Very cool results so far. We will get the final products on Wednesday.
