Rainbow Slime

|

These past two weeks, the kids and I have been working a lot with rainbows. We’ve been exploring their symbolic significance, their beauty, and their order, but we’re still working on getting the colour sequence correct so I thought something a bit more hands-on might help them remember and whipped up some rainbow slime.

Rainbow Slime: Teach Kids the Order of the Rainbow Using this Fun Sensory Play Activity

I had four preschoolers that day, so I decided to make 1 cup of each colour of slime so that they could all have a few opportunities to roll their own rainbows.

Before we get to the recipe, I had to tell you that it’s finally here! I wrote The (Ultimate) Slime Book oozing with over 50 pages of stretchable, squishy sensory fun – including a year of seasonal slimes, edible slimes and unique ways to play with slime. Click here to get more details.

You can purchase The Slime Book on Amazon, Book Depository, or at your local bookstore!

For each colour of the rainbow slime I mixed:

Or, if you prefer saline solution slime:

Knead the slimes for at least a minute to check their consistency as it will change (just like homemade play dough does) with a bit of play.

If you’ve never played with slime before, don’t worry about a sticky disaster! If it’s made properly, it will be stretchy and gooey but not sticky.

Slime can require a bit of experimentation and patience, especially if youโ€™re still new to it. If you run into any slime fails, check out this troubleshooting post to help fix your slime.

I ripped small amounts of slime in each colour for each of the kids and showed them all how to assemble their own rainbow — and how pretty and stretchy it would be!

 

They immediately set to work rolling out “snakes” of each colour and attaching the colours in order – Red, Orange, Yellow, Green, Blue, Purple.

 

 

I was honestly shocked at how well most of them remembered the order of the rainbow during this activity, especially considering the paintings made just the day before were a bit more creative in their colour orders! It just goes to show you the power of sensory play and how sensory stimulation can help with deep semantic learning.

 

 

After they had assembled their rainbows, they stretched, squished, poked, snapped, and flattened their rainbow slime. Eventually they all ended up with giant rainbow slime balls… which were pretty for about two minutes until they turned into a glittery, brown slime ball. Luckily, I had made enough slime that the children were able to make three more rainbows before we moved on, and we still have a bit of slime left over!

Left Brain Craft Brain has a cute glow-in-the-dark slime recipe which would be a fun twist on this activity if you could get the paint that she recommends in all 6 colours!

We loved playing with our rainbow slime, I hope your kids will, too!

  1. Okay. THIS IS THE COOLEST THING EVER! I will have to do this with my tots. I might ending having as much fun as them. this is going on my to do list!

        1. I think about a teaspoon? There’s a lot of kneading involved with making slime, so you might add a bit more if the glue is still sticky after a good kneading of the ingredients.

  2. Hmm it looks like your blog ate my first comment (it was extremely long) so I guess I’ll just sum it up what I submitted and say, I’m thoroughly enjoying your blog.

    I too am an aspiring blog writer but I’m still new to
    everything. Do you have any tips for first-time blog writers?
    I’d really appreciate it.

    1. Honestly, I think just writing what you know and are passionate about – and if those things aren’t the same topic, write about what you are passionate about! Write every day, or as often as you can. Figure out your voice, your focus, and what will keep you passionate about writing your blog long-term. Everything else will work itself out.
