This homemade magnetic slime recipe is EASY to make but requires adult supervision.

Last year my son sold slime at a kid’s entrepreneur event and spent months perfecting his slime recipes. This easy to make homemade magnetic slime recipe is by FAR his favorite and a stronger magnetic slime than any slime we have found on the market to buy. He has made a lot of batches of slime trying out the best strength for magnetic slime and this one is the winner! (Looking for even more sensory ideas? Join our sensory Facebook group here!)

Magnetic Slime Directions:

In a medium bowl:

1. Add 1/2 a cup of white school glue.
2. Add 1/2 cup of shaving cream.
3. Add one tablespoon of cornstarch.
4. Add 3 pumps of any Hand/Body Lotion.
5. Mix the four and add 1/2 a teaspoon of black iron oxide powder*.
6. Add half 1 1/2 a cup of liquid starch to a container mix and let it sit for 30 minutes.
7. Add the rest and mix well.
9. Play with the slime!

*TIP – I strongly recommend adult supervision when opening and using black iron oxide powder! It can be easy to accidentally inhale and you will want to hold the bag far away from your face as this is an iron filling. You do NOT want any powder dust near your face! Once it is mixed thoroughly into the slime it is OK to use!

This magnetic slime stores AWESOME in any airtight storage container. My son has kept his for up to 6 months or more with no issues. Although you might be tempted to add a ton more iron filling to see how fast your magnetic slime can move I’d add the word of caution that the black iron oxide powder can tend to leave black marks on your hand if you are using it in too high of a quantity! This recipe does NOT leave extra fillings or colors on your hands!

Any size magnet works but we bought a super strong square magnet for a bigger WOW effect! It’s unbelievable – it looks like a blob from a movie just crawling up and around the magnet! My son was incredibly excited because he had purchased magnetic slime before and it was so lousy compared to this homemade magnetic slime recipe he created!

TRY IT OUT!

Roll a bit of your magnetic slime up like you see above and hold your magnet ABOVE it. We were able to make our magnetic slime “WAVE” back and forth as we moved the magnet in an arch pattern above the slime! You can see this magnetic pattern shown in the video!
