Let’s learn how to make magnetic slime!
Magnetic slime just might be the coolest slime recipe we’ve made yet, and you know how much we love making homemade slime. This magnetic slime recipe is part science experiment, part magic and part slime fun!
The slime’s secret ingredient is black iron oxide powder…
My son played with this magnetic slime stuff for hours — he loved setting our magnet on the slime and watching it get swallowed up. He watched while setting the magnet near the slime and watching it crawl toward the magnet.
It just really is that cool!

How to Make Magnetic Slime
Supplies Needed to Make Magnetic Slime Recipe
- 6 oz white school glue
- 1/4 cup water
- 1/4 cup liquid starch
- 2-4 tsp black Iron Oxide powder
- Neodymium Magnet
- Medium sized mixing bowl
- Something to stir with
Directions to Make Homemade Magnetic Slime
Step 1
Add the school glue to a bowl and stir in the water. Once it’s fully incorporated, add the liquid starch, and stir until it starts to come together.
Step 2
Remove the slime from the bowl and knead it, stretching it to make it more pliable.
At this point, you have a bunch of white slime.
Yay!
Step 3
Now it’s time to add the Iron Oxide powder.
This is what makes the slime magnetic!
Make a small indention in the slime and add a teaspoon of Iron Oxide powder.
Step 4
Fold the slime over the powder and knead it to incorporate the powder throughout.
The slime will turn black.
Repeat the process to add enough powder that the slime reacts to a neodymium magnet.
You can see how the magnet will pull some of the slime from the rest stretching the black slime.
What is a Neodymium Magnet?
It is a rare earth magnet or a permanent magnet made from neodymium, iron and boron. Because they are very strong, be careful when using two together. They can strike each other forcefully. You don’t want to be pinched in the middle.
Watch how the magnetic slime “swallows” up the magnet!
See how far you can twist and pull the slime without it breaking.
Isn’t it fun?
