MagnetismĪ magnet is a material that produces a strange, attractive force around it called a magnetic field. When mixed with glue, the borate ions cross link with the glue’s protein molecules, creating larger molecules that can no longer easily slide past each other and create a thick gooey substance. Liquid starch contains sodium tetraborate. These chains are able to slide past each other making the glue flow. The Science Behind Magnetic Slime PolymersĪ polymer is a substance made up of a long chain of molecules that repeat. As soon as rust appears please discard the slime. Storage note: You may store this slime in a small container however it will rust. Now for the good part: Place your magnet on top of the slime and watch it disappear! Step Five Once the slime is mixed it’s time to experiment! Hold a neodymium magnet close to the slime and watch what happens.Note that the metal in this recipe makes the slime stiffer than typical slime with a grainy texture. If it is too watery add in a small amount of glue. If your slime is too sticky add in a little bit of liquid starch and knead. Knead until it no longer sticks to your hands. Step Four Once the slime begins to pull away from the sides of the bowl start kneading it with your hands.Step Three Slowly pour in 1 ounce (2 tablespoons) or liquid starch stirring as you add it in. ![]() Step Two Add 1 tablespoon of both black iron oxide powder and iron filings.Step One Add 2 oz (¼ cup) of white glue to a small bowl.Gloves (recommended to keep hands clean when mixing and for people with sensitive skin).Liquid Starch (laundry detergent may be substituted).You may omit the iron oxide powder but your slime will be a gray color and may be stiffer than the combination of iron oxide powder and iron filings.The iron filings are highly magnetic but make the slime very stiff.The black iron oxide powder gives the slime it’s color and is somewhat magnetic.Here is the safety sheet on black iron oxide If you are making this with anyone who has sensitive skin please wear gloves. It may also cause skin irritation though we did not have any issues with this. Mix it into the wet slime to avoid generating dust. Iron Oxide Powder is used in ceramics, chemistry, and magnetic slime.Also these magnets are extremely magnet and can pinch you if they are held close to another magnet! Keep individual magnets well separated from each other! Neodymium magnets are extremely dangerous if swallowed.I recommend using this size.Magnetic slime is sure to get kids interested in learning about the incredible invisible force of magnetism If you have been following my blog you know that I love sharing weird and wonderful projects that get kids and adults excited about science and STEAM. In fact, the kids showed us the trick of placing the magnet in the slime to watch it disappear! Kids LOVE making it! We recently made this in a workshop and attendees really really enjoyed playing with this slime.It is so cool to watch! It looks like some type of alien gobbling up magnets. Yup, as in the magnets are quickly attracted to and surrounded by the slime. Okay now that I’ve told why you shouldn’t make it here’s why you SHOULD: I think of it as a one day only type of slime. ![]() In a day or two this slime will turn brown with rust. Guiding strands of slime through the air using the force of magnetism is not as easy as some magnetic slime videos look.
