    What I love about making slime is that you are truly only limited by your imagination. There are so many items you can add to your slime to make it a whole new sensory experience. 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.

    Learn how to make rock slime for kids. It is easier than you think and kids will delight in the texture.

    For more fun with rocks check out these Rock Activities and this this Panning for Gold Activity.

    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 teaspoon baking soda
    1 tablespoon contact solution
    Small Rocks
    Small bowl

    ingredients for how to make rock slime

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

    pouring clear glue in a bowl

    Stir in ½ cup of water into the glue.

    Now, add in ½ teaspoon 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.

    mixing rock slime

    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!

      I am sure that some kids would love this, but it kind of geeks me out. I hope my kids don't catch on to this slime trend.

      Well, this is an awesome idea. My 3 year old daughter is at the perfect age for activities like this and I know I have some construction trucks lying around from when my son was younger. This is going to be fun!
