This molten lava slime is perfect for all kinds of science and sensory play. We especially loved using it with Star Wars Lego characters and dinosaurs. How will YOU and the kids use it?

My son and I originally made this molten lava slime years ago. Take a look at it in action:
We were inspired by the scene in Star Wars: Revenge of the Sith where Obi-Wan and Anakin duel on the planet Mustafar.
The planet has lots of active volcanoes, so the two fight amid pools of hot lava.
Obviously, you need to decide if the scene from the actual movie is appropriate for your own kids.
This post is focused on sensory and pretend play with slime! Seeing the movie isn’t necessary.

How to Make Lava Slime
This slime is made up of four batches of slime – yellow, red, orange, and gold. You can find the individual recipes below.
The children can help with measuring, mixing, and setting up this slime activity . . . provided they’re under adult supervision the entire time. And as long as they’re old enough to keep things out of their mouths.
You can even outfit the kids with their own safety goggles, aprons, and gloves for slime making.
My son was 7 when we first made our lava slime. He was involved in it from start to finish.
Lava Slime Materials
Here are all of the items we used to make our molten lava slime.
If you and the kids love making slime, I suggest designating a set of mixing bowls and measuring cups just for slime.
Liquid watercolors (or food coloring)
Craft sticks or spoons
How to Make Red Slime
Start off by making the red portion of the lava slime.
Add 5 ounces of clear glue to a mixing bowl. If you like adding water to your slime, you can add about 4 ounces of water to the glue.
Then mix in 1 tablespoon of red liquid watercolors and 1 tablespoon of red glitter. Stir everything well.
Slowly add 4 ounces (about 7 to 8 tablespoons) of liquid starch to the bowl. Stir well as you add the starch.
Knead the slime for a minute or two, and then check the stickiness and stretch.
If more starch is needed, be sure to add it in a tablespoon at a time before kneading.
How to Make Orange Slime and Yellow Slime
Next are the orange and yellow slimes.
To do so, follow the same basic directions as the red slime above.
The only thing we did differently was the addition of glitter. We put glitter in the red slime, but chose not to add any glitter to the orange or yellow slimes.
You can, of course, add glitter to these slimes if you want to!
How to Make Gold Slime
I have to admit, this one is a favorite of mine. We have made it SO many times over the years. And it never fails to be a blast.
It’s the perfect addition to the lava slime, as it adds just that extra bit of golden glimmer.
You can read here how to make the golden slime:
Assemble the Lava Slime
Once you’ve made the red, orange, yellow, and golden slimes, it’s time to put it all together!
Have the kids place the slimes on top of each other on a large tray or platter. The order doesn’t really matter – let the kids decide for themselves.

From there, add any of the items you’d like to include in your lava slime.
You might add Lego Star Wars minifigures, toy dinosaurs, or even a toy volcano.
Then let the kids play and explore to their hearts’ content!
How We Played
Once the slimes were ready to go, my son brought in his Lego bricks and minifigures.
If your children are really into Star Wars, I’m sure they’ll enjoy it too.
We used a variety of minifigures with the lava slime:
- Our own hobbled-together version of Anakin
- Some random Lego bricks
We didn’t have all of the “correct” Lego items, but that wasn’t a big deal.
My son ran a few different experiments with the slime, mostly focused on how long Lego take to sink.
And of course there was a LOT of stretching the slime and poking it. Because how can you not?!

From there, it was an epic bottle over the lava slime.
At the end of our duel, Anakin was left to sink into the molten lava.
The slime bubbled and everything, which added even more dramatic effect to our play.
Once the Lego Star Wars duel was over, most of the slime was mixed together. This resulted in a beautiful, sparkly dark orange slime.
We sealed it up in a lidded container and continued to play with it for weeks.
The lava slime was perfect for our small dinosaur toys, along with a wide range of other toys.
Are you up for making molten lava slime with the kids? If so, be sure to let me know how much fun you have.
