This homemade magnetic slime recipe is EASY to make but requires adult supervision. Below you’ll learn how to make magnetic slime plus find other easy magnetic activities for kids!
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 recipe is the winner! (Looking for even more sensory ideas? Join our sensory Facebook group here!)
Magnetic Slime Recipe Ingredients:
1/2 cup of Elmer’s School Glue
1/2 cup Shaving Cream (NOT shaving gel, just cheap regular shaving cream)
1 Tbsp. Cornstarch
3 pumps any Hand or Body Lotion
1/2 tsp. Iron Filling (Buy a small bag here or a large bag here)
1.5 cups Liquid Starch
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, mix, then add any remaining starch as needed for the perfect consistency, and let it sit for 30 minutes.
7. Add the rest and mix well.
9. Play with the slime!
This magnetic slime recipe 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!
*NOTE – over time the iron oxide will separate in the slime mixture. All you need to do is stir it up or mix it well and your slime will be as good as new!
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!
