Magnetic slime is a hands-on blend of creativity and science! Made with iron oxide powder, it’s stretchy, squishy, and full of magnetic surprises. A fun way for kids to explore STEM through play!
Pour in 1/4 cup water and stir gently, until well combined.
Add 1-1/2 teaspoons baking soda and stir well, until dissolved.
Step 3: Add the iron oxide
Add 1/4 cup iron oxide powder. This is what'll make your slime magnetic.Be careful not to touch the plain powder with your bare hands, as it can cause skin irritation. Wear gloves if you're worried about touching it before it's activated in the slime.
Stir well, combining the powder into the glue mixture.It'll start off grey and look like forbidden cookies and creme, but as you continue stirring it becomes a really deep black.
Step 4: Activate the slime
Pour 2-1/2 teaspoons contact solution into the bowl.
Stir and stir, until you can't stir anymore. The slime will thicken and come away from the bowl.
Pick up the slime and knead it, stretching it to fully work in the activator. It will be sticky at first.
Continue stretching until the slime is no longer sticky. Add a few drops of contact solution at a time, if needed.
Your magnetic slime is complete!Now have fun bringing magnets near it and seeing how it moves! You can also set a magnet on top of the slime and watch it get "eaten"!
