i tried this demo for the first time this year. It didn't work perfectly but it really gave the students a visual of the formation of minerals. I would suggest marking the water level on the jar when you first set it up so they can really grasp how much has evaporated by the end. I let mine sit for almost 3 weeks but crystals were forming within 3 days.
