Growing crystals

Last week we tried and completely failed to grow sugar crystals. I don't think I had the water saturated enough. This week we moved on to salt.


We decided to try table salt, rock salt and Epsom salt. The Epsom salt dissolved the most easily. The rock salt was rather difficult to dissolve.


We made shapes with pipe cleaners and hung them in the jars. We labeled our jars and will wait a few weeks to see what happens.


So far the Epsom salt jar is growing crystals but the other two aren't doing as well. The water will be more and more concentrated as the water evaporates, so we'll see what happens.
