• Water

The first step in making magnetic slime is to extract the metal from our breakfast cereal. As stated earlier, you can use whatever kind of cereal you want (I used Cheerios). But if you look at the nutritional label you can check just how much iron is in you cereal. It just so happens the cheerios I used contained 45% Daily Value of iron. There are certain cereals that contain 90% Daily value of iron and would result in much more iron being extracted from the cereal.

The Process

The process is simple. Pour the cereal into a blender, fill it with water, and blend it until it turns to mush. Once you are done blending, pour the cereal into a big enough bowl that will contain the mixture, and also allow for you to move your hand around in it without making a mess. Allow the mixture to sit for about 5 minutes to allow everything to settle.

Once you have your mixture in a bowl, place your neodymium magnets into a ziploc bag. This will allow you to attract all of the metal in the cereal and easily remove it from the magnets in the next step.

Now that the magnets are in a ziploc bag, place the magnet into the bowl of blended up cereal. Move the magnets around the blended up cereal continuously for approximately 2-5 minutes (the longer you do this the more iron you will collect). Once you take the bag of magnets out you will be able to see the iron metal that the magnets have collected from the cereal.

After you have collected as much iron from the cereal as you can, gently dunk the bag of magnets into a lean glass of water. This will wash away all of the cereal from the bag and leave you with just iron filings on the outside of the bag.

Grab a piece of paper (a clean table top will work as well) and set the ziplock bag on top of it. Open up the bag and remove the magnets. Once the magnets are out of the bag, you can begin to gently tap the iron filings off of the bag and on the the paper surface. This will take a little while due to the fact that the iron filings are wet and want to stick to the bag. After you have removed all of the iron filings, allow them to dry for approximately 20 minutes.

After the iron filings have dried, place the magnets into a new (dry) ziplock bag. Rub the bag of the filings to allow them to collect to the bag. Once you have all of the iron filings collected, place the ziplock bag over a new piece of paper, remove the magnets, and allow the iron filings to fall into a nice dry pile. Placing the iron filings on a piece of paper will allow you to transfer them to the slime later on.

The next step in the process is to make the slime.

For this part you will need:

• 1 Bottle of Elmer's glue
• 1 Bottle of Elmer's glue full of water
• 1/4 cup of water
• 1 TSPN of Borax
• A mixing bowl for the glue
• A mixing container for the Borax solution

The Process

Pour an entire bottle of Elmer's glue into a bowl. Fill that empty bottle of Elmer's glue up with warm water, and pour that into the bowl as well. Mix the glue and water until you can no longer see the water separated from the glue.

In a separate container, add 1/4 cup of warm water and 1TSPN of Borax powder. Mix them together.

Now go back to the bowl that contains the mixture of glue and water. Begin to stir the glue and water mixture and slowly add the borax mixture until they are all combined in one bowl. Stir the mixture for several minutes until it begins to stick to the spoon. At this point you will see the slime begin to form. Once the slime begins to stick to the spoon, it is time to get your hands dirty. Continue to mix with your hands until you no longer see any residue on your hands. Once the slime no longer sticks to your hands, and can easily be stretched and folded, it is complete!

This step is easy.

Lay your slime on a flat surface and stretch it out a little bit. Pour the metal filings we collected from the cereal onto the top of the slime. Fold the slime over on top of itself, pick it up, and mix it together with your hands for a few minutes. With the relatively small of amount of iron collected from the cereal, I found that it wanted to collect in one small spot and not really spread throughout the entire slime. The filings condensed to a small area actually helped the magnets attract the slime and made it a little more fun to play with in the end.

The time has come.

Place your slime on a flat surface. Grab your neodymium magnets (no ziplock bag required) and have some fun. As stated earlier, my iron filings condensed to a small area of the slime which made it easier for the neodymium magnets to attract and manipulate the slime. If you wanted to, you could extract iron filings from multiple boxes of cereal that way you could make a bigger pile of magnetic slime.

Or, if you don't feel like going through the hassle of extracting the iron filings from cereal, you can just order some from amazon by clicking on this link: http://amzn.to/2qizWW4
