Have you ever thought about adding rocks to slime? The results are so much fun! Find out how to make rock slime that your kids will adore. Don’t forget to check out our other Easy Slime Recipes.

Please supervise your kids when making slime and have them wash their hands when they are done playing. This is not edible.

How to Make Rock Slime

You will need:

1 airtight container – I love these slime containers!
1 five oz bottle of clear glue
½ cup water
½ tsp baking soda
1 tbsp contact solution
Small Rocks
Small bowl

To make rock slime, start by pouring a 5 oz bottle of clear glue into a large bowl.

Stir in ½ cup of water into the glue.

Now, add in ½ tsp baking soda and stir.

Now it is time to add in the rocks. Kids will love pouring the rocks into the bowl.

And finally, it is time for the magic to happen! When you add 1 tablespoon of contact solution to your mixture, the slime will instantly begin to form.

Mix everything together. This mixture will be very sticky, so be patient. Mix the solution in the bowl until it starts to form.

Slime requires way more mixing and kneading that you might think. Keep kneading the slime until it is no longer sticky.

If you want to add additional rocks at this point, go ahead! My girls are huge fans and collectors of rocks, so for them, the more rocks the better.

With all these rocks, this slime is quite heavy. The weight from the rocks will cause the slime to cascade and stretch, but it is fun for molding into shapes too!

When your kids are done playing with the slime, you can store it in an air tight container like this one.

I recommend playing with slime on a table or tray. Do not play with slime near carpet as it can very hard to get out if some falls on the rug.

A fun addition to this rock slime are small toy trucks like these. Kids can pretend like they are working on a construction site!

Looking for more fun activities to do with your kids? I highly recommend KiwiCo, which you can enjoy no matter the weather. As a former teacher, I was really impressed with the quality of materials found in KiwiCo. Some moms have told me that they want to do activities like I do on Mess For Less with their kids, but they just don’t have to the time to go buy all the supplies and prepare them for the activity. KiwiCo is the perfect solution. Every month your KiwiCo will focus on a particular theme like Colors, Dinosaurs or Gardening. KiwiCo offer a variety of projects ranging from crafts, imaginative play, science experiments and more.
