How to Make Slime

Four Methods:Basic Slime"Living” SlimeEdible SlimeSoapflakes Slime

Slime is always popular with the kids and the reason why is simple — it's lots of fun! It is much cheaper to make at home, and easy to do. Here are three different exciting ways to make different kinds of slime.


Basic Slime

  • ½ cup of craft glue
  • ½ cup of water(warm)
  • Food coloring (optional)
  • 1 tablespoon borax powder

"Living" Slime

  • ¾ cup cornstarch
  • 2 cups vegetable oil
  • A piece of styrofoam

Edible Slime

  • 1 can (14 oz.) of sweetened condensed milk
  • 1 tablespoon of cornstarch
  • 10-15 drops of food coloring

Soap flakes Slime

  • 1 cup soap flakes
  • 4 cups hot water
  • Food coloring (optional)

Method 1
Basic Slime

  1. Image titled Make Slime Step 1 preview
    Mix one tablespoon of borax powder with one cup of warm water. Make the mixture in a quart (950 ml) jar. Continue to stir it until the borax is completely dissolved.
  2. Image titled Make Slime Step 2 preview
    Take a second jar. In this jar, mix together ½ a cup (4 oz.) of glue and ½ a cup (4 oz.) of water. This should produce a watery, cohesive solution.
  3. Image titled Make Slime Step 3 preview
    Add food coloring to the watery glue mixture. Choose any color.
    • You can also separate the glue mixture evenly into smaller jars and make each one a different color.
  4. Image titled Make Slime Step 4 preview
    In a large jar, mix the borax solution into the watery craft glue solution, and watch the slime form.
    • If you chose to make smaller amounts of slime in separate containers, evenly divide the borax solution among the containers.

    Let it sit for 30 seconds. The 30 seconds will give the slime time to solidify.

    Take it out and have fun!

Method 2
"Living” Slime

  1. Image titled Make Slime Step 7 preview
    Mix ¾ cup (175ml) of cornstarch with 2 cups (475ml) of vegetable oil. Mix it thoroughly in a tumbler or other glass.[1]
  2. Image titled Make Slime Step 8 preview
    Place the mixture-filled glass in the refrigerator. Leave it in the refrigerator until the mixture is chilled. This will help it to solidify.[2]
  3. Image titled Make Slime Step 9 preview
    Remove the mixture from the refrigerator. Stir it well (the ingredients will have separated again). Let the mixture warm up just enough that it flows slightly.
  4. Image titled Make Slime Step 10 preview
    Find a block of styrofoam. It can really be any size but the standard size is 1 by 6 by 6 inches (25x150x150mm). Run the styrofoam on your hair (or really anything that will give it a charge- a rug, a dog, your child, etc.) The point is to build up a static charge.[3]
  5. Image titled Make Slime Step 11 preview
    Tip the container of slime so that the slime flows slowly out of it. (It should flow slowly.) Place the piece of styrofoam just in front of the slime. It should be about 1-inch away from the flow of slime. The slime should stop flowing and appear to take on a life of its own. Wiggle the styrofoam around and the slime should follow it. Your kids will be amazed (and you will be too!)[4]

Method 3
Edible Slime

  1. Image titled Make Slime Step 12 preview
    Pour a can of sweetened condensed milk into a pan. Add one tablespoon of cornstarch to the mixture and stir.[5]
  2. Image titled Make Slime Step 13 preview
    Bring the mixture to a low heat. Continue to stir constantly. If you don’t, the mixture may stick.[6]
  3. Image titled Make Slime Step 14 preview
    Remove the mixture from the heat when it has thickened. It should be more gelatinous and harder to stir.[7]
  4. Image titled Make Slime Step 15 preview
    Add 10 to 15 drops of food coloring to the mixture. You can choose any color. Allow the mixture to cool before you let your kids play with (and eat) it.[8]
    • Make sure that the slime does not get on anything that stains easily or that you want to keep unstained. The food coloring in the slime may cause it to stain lighter colored things.[9]

Method 4
Soapflakes Slime

  1. Image titled Make Slime Step 16 preview
    Dissolve the soap flakes in water in a large bucket or bowl.
  2. Image titled Make Slime Step 17 preview
    Add color if desired.
  3. Image titled Make Slime Step 18
    Let stand for up to 1 hour.
  4. Image titled Make Slime Step 19 preview
    Beat. The resulting play material will froth up when beaten. It pours easily and is extremely slimy to touch.
  5. Image titled Make Slime Step 20 preview
    Keep in an airtight container. This slime keeps very well, away from direct sunlight and heat.


  • When you add food coloring, make sure you mix it well or it could cause a different reaction.
  • If you add color to the slime, it may stain things.
  • Make sure your kids don't get the slime on certain things (ceiling, walls, carpet, furniture, etc.).
  • Don't put slime on carpet. It will stick.
  • The recipe can be modified by varying the proportion of the ingredients. For example, if 2 parts borax solution are used, the slime that forms is "harder" and less gooey.
  • If you put it in a cup and press down on it, the slime makes a funny sound.
  • If you choose to use corn starch instead of borax, make sure that the corn starch is not very lumpy, so that it mixes better.
  • Keep the slime away from pets and small children.
  • If you don't want to use borax, try using corn starch.
  • You can add essential oils or scented liquid soap to the slime to make it smell nice.
  • Wash your hands after playing with the borax slime. Borax slime is acutely toxic, so not enough to hurt you, however it may pick up dirt and gunk that you don't want to ingest.
  • If you don't want to let it sit, mix it a little, then empty out the excess water (the more you leave it in the water the slimier it gets), and then continue mixing with your hands.
  • Elmer's glue is one suitable brand of glue. It is more generally known as poly(vinyl acetate).
  • Make sure all the ingredients are well dissolved.
  • For a good and easy way to make slime, just add glue, laundry detergent, and some food coloring, and mix it up.
  • This solution is best enjoyed on the day of creating it. The slime will gather fluff, dust and particles that make it unpleasant to keep.
    • However, if you do wish to store it, label it well to avoid any confusion as to what it is and keep in a cool place.


  • Borax is poisonous if swallowed. Do not ingest and do not permit children to do this. Please follow instructions responsibly.
  • Glue should not be ingested or sniffed.
