Do your kids love slime? Mine do now! I bet you've seen the trend going around of all these variations of homemade slime with the latest craze - magnetic slime. My boys love magnetic slime because it's so much more interactive than regular slime. It's a great way to teach kids about magnetism while having fun at the same time. Magnetic slime is made by adding iron filings to any recipe of homemade gooey slimes. We made slime by mixing Elmer's (PVA) glue, shaving gel and liquid laundry detergent.
