Salt crystal experiment

Sara wanted to do some more science experiments, so I told the girls to look up some up online. We struggled to find one we had all the equipment for, until I came across one that only needed water and salt. I told the girls to read the intructions  and they did everything they could by themselves. After a few days, the salt in the water started to turn into crystals – now, a week and a bit on, they have grown even  bigger! Almost all of the water has now turned into crystals!
