Homemade Magnetic Slime



About: I am a teacher outside of Boston and I love making cool stuff! Any prizes I'm lucky enough to win will go directly to my classroom (when appropriate) where I teach 6-12th grade English & Social Studies (...

There are TONS of slime recipes online. Some great and some not so great. During our summer school program I decided to have some of my kids experiment with different types of slime recipes and ingredients. They all started with a base recipe and then changed it as they tried different things. This recipe is one we came up with for magnetic slime.

Step 1: BoM

White glue


Iron Oxide

Strong magnets

Water (warm/hot)

Food coloring (optional)

Craft sticks

Step 2: Glue

Mix 4-6oz of glue with 1/2 cup of warm water. If you want color, this is the time to add it.

Step 3: Borax

Mix 1 tsp of Borax with 1 cup of warm water.

Step 4: Mix

Slowly pour the Borax water into the glue cup and mix as much as you can. Remove the clumpy mixture from the cup and knead with your hands.

Step 5: Iron Oxide

When the slime has been kneaded a bit, add the iron oxide (start with a tablespoon) to your slime and knead it

Step 6: Test!

Using magnets (the more powerful the better) test your slime! We have weak magnetics so we were not able to get the slime to move on its own, but the magnets did stick to the slime, which was pretty cool.
