Ever since I was a little girl, I loved rocks and crystals of all sorts. So I was happy when my mom and I started a salt crystal experiment. We got this recipe from Science Arts, a book recommended in our curriculum. The author apparently did not try her experiment because she said that it would be done in a maximum of three days. It took at least a month. I’ve given you some pictures over the stages of progression.
During the time it took for the crystals to form, I actually learned a lot! If part of your project is not immersed in water, big, bulky blobs of salt crystals will migrate up and make themselves at home on your pipe cleaner, and pencil. The migrating salt crystals, which look like warts that are squashed together, are different from the ones in water, which are small, graceful, and are in the thousands.
The fact that the author didn’t try the experiment makes her unreliable. An alternative to this experiment is to use borax which will grow over your pipe cleaner in less than 24 hours. I am always impatient which is not useful in life. So all you have to do for fast growing borax crystals is go to www.thediscovery.org, where you will find instructions.
Personally I think the experiment was interesting, but I wouldn’t recommend it, because it takes a long time and it’s not that beautiful. If you want fast growing crystals, try borax not salt.
