Play Recipe: Sparkly Rainbow Crystals

Hi friends! Today I thought I’d share a fun play recipe that we have been keeping busy with this week- sparkly rainbow crystals! They are super easy to make and we’ve been using them for all kinds of sensory play and art activities.

I’m not even exaggerating when I say that the twins (age 3) are completely fascinated by our rainbow crystals. They call the stuff “wonderland snow” and have loved every activity we’ve done with it. Seriously- to the point of wanting to take wonderland snow to bed with them.

I’ll be sharing our rainbow crystal activities soon, but in the meantime I thought I’d share the recipe so you can make your own if you’d like to play along. Are you ready for this? You only need two ingredients (yes, just two)…

That’s it! One almost-full box of ice cream salt yielded plenty of colorful goodness. I simply split the salt between five different gallon-size freezer bags, put a few squirts of liquid watercolors in each bag (for five different colors), massaged each bag to coat the salt (only took a minute or so), and then spread the salt on foil-lined cookie sheets to dry. I checked about an hour later and the salt was totally dry and ready to rock!

Obviously, use common sense with this material. If your little one is still mouthing, save it until they are older because you don’t want them ingesting watercolors or large amounts of salt. We didn’t have any issues with the watercolors transferring back onto our hands or clothing from the salt, but be cautious until you know that your crystals are thoroughly dry. Other than that, you should be good to go!  Wanna see what we did with the crystals? Check out these posts: Rainbow Crystals on the Light Table

  1. I wouldn’t have thought of rock salt as a sensory material – and definitely wouldn’t have thought to color it. It’s so pretty, no wonder your twins love it!

  2. We do the same thing with table sugar is a cheap cookie decorating solution!

      Definitely! Although hopefully you aren’t using liquid watercolors, hah! I prefer those for dying things once kiddos are past the tasting phase 😉

  3. This looks like so much fun! I’m always on the lookout for new sensory materials and I know my kiddos would love this! I don’t have liquid watercolors, so I’m hoping that food coloring works just as well. Thanks for the great idea!

  4. I need to make this ASAP! Love this idea! Gorgeous colors!

  5. This is fabulous!! Love all your rainbow stuff, Stephanie. :)

  6. This is lovely! I can’t wait to try this, I’m sure my little girl would love it too. Thanks for sharing :)
