Thanks! We had lots of fun with my 3 and 5 yr old. The 3 year old went straight for his magnifying glass! We are going to try the sun catchers now.
Other Tips for leftover liquid: throwing it in the bath! Or, use in it sidewalk cracks for a long lasting kid-safe weed killer (just don’t use it where you want plants to grow later).

Very pretty. Thought you might be interested to know that they use epsom salt to make the pretty icy window special effects in the movie business. Not sure the recipe, but they dissolve epsom salts in beer (don’t know why, maybe it evaporates quickly?) and use a paint brush to paint it around the edges of a window to make it look icy or over the entire glass to frost a window.

In reply to Sarah. Best to dry them indoors away from moisture :)

I’m hoping to try this at work with my preschoolers. Do you think it is ok for the lids to be covered while out in the sun? It’s kind of rainy where I live and I wouldn’t want them getting ruined…. Or perhaps, can they dry indoors?

Hi Gina,
I would have one lid per child 🙂 Maybe you can get parents to bring in a few clear plastic lids?

Hi, I know you said several lids up above when you were making it. Do you think that would be about 4-5 lids at a time? I’m trying to figure out doing this for about 20 kids at a time.

In reply to Paige. Sounds like fun Paige! I did find that the crystals tend NOT to absorb color though. Crystallization is a process of purification so the color will most likely not work on the crystals themselves but perhaps the surrounding water or plastic will be tinted.

I’m thinking of doing this at the nursing home but adding a bit of liquid watercolor to it to make it easier for them to see. I love the way the crystals look on dark paper too when painting with the mixture. Thanks for sharing!
