To make crystals we needed vinegar, baking soda, and a hot plate. We mixed a little bit of baking soda with vinegar into a tray and put it on a hot plate, and after heating it up, the vinegar started to stink really badly, so we put it under the fume hood.
At the end of the period it was ready to be taken off of the hot plate, and we kept it in the fume hood to cool off over the weekend. On Monday when we came back, it was crystalized. We took the crystals out of the tray and cleaned them off with water.
