Whether you’re making this as a fun science project or just want to wow your kids with something amazing, this DIY magnetic slime is sure to be a hit. We’ll show you how to make magnetic slime step-by-step, with the exact ingredients you need. So grab your supplies and let’s get into this positively magnetic activity!

Helpful Tips:

What makes magnetic slime magnetic?

Magnetic slime gets its “superpowers” from a special ingredient called iron oxide. This powder is made of tiny particles of iron — yes, the same kind of metal that magnets stick to! When you mix the iron oxide into your slime, it spreads all throughout. The iron particles don’t make the slime magnetic on their own, but when you bring a strong magnet close (like a neodymium magnet), something really cool happens. The magnet pulls on those tiny iron bits, and the slime starts to move! It might stretch, wiggle, or even crawl toward the magnet. It looks like magic, but it’s actually science in action! The iron in the slime is reacting to the magnetic force, making your slime do things regular slime can’t. This is what makes it so fun to play with!

What type of magnets work with magnetic slime?

Regular magnets aren’t strong enough to move the slime. You’ll need neodymium magnets, also known as rare earth magnets. We attached the neodymium magnets to a horseshoe magnet for pictures, but by itself this magnet won’t affect the slime. For best results, use larger neodymium magnets like a bar or cube. And be cautious, because these magnets are very strong. They can snap together quickly and pinch fingers, or even break if they collide too forcefully.

Is iron oxide powder safe to touch?

In small amounts, iron oxide is non-toxic, but the powder form can be harmful if inhaled or ingested, and may irritate skin. Once the slime is fully mixed and activated, it’s safe to touch unless you have very sensitive skin or cuts on your hands. In that case, it’s best to wear gloves while playing. And there you have it: magnetic slime that stretches, wiggles, and “magically” moves with a magnet! Whether you’re diving into a science lesson or just looking for an awesome twist on regular slime, this experiment is sure to attract a lot of attention (haha). It’s soft and stretchy, packed with hands-on fun like regular slime, but the science behind it makes it even cooler! So grab those magnets, mix up your slime, and get ready to wow the kids with this seriously magnetic activity.
