Lava Slime Directions
Creating a lava slime recipe is a lot of fun! Here’s how to make lava slime:
Lava slime is made from black volcanic rock slime and neon yellow “magma” slime.
You’ll need to mix both colors. I used the same recipe for both slimes.
For black: Mix 1 part white glue with a squeeze of black paint, soap dye, or food coloring in a pinch. If you do use food coloring, you’ll probably have to use a lot of dye to keep it from being grey and not black.
Add 3/4 of a part of liquid laundry starch and mix. Once the slime is stretchy and no longer sticky, it is ready and you can set is aside. You can add more laundry starch if it feels too sticky.
Humidity will affect how sticky your slime is.
For yellow: Follow the same recipe as above, just dye with yellow colors.
Once both slimes are ready to go, you can add globs of yellow slime on top of the black slime. This creates a lava/magma appearance that is a lot of fun!
The slime will mix quickly, so you won’t have lava slime for long. You can keep the colors separate longer by avoiding stretching it too much.
You can also make small batches of lava slime by adding just a small amount of your yellow slime to the black slime at a time so that you can play with it for longer.
