Make Slime

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

Steps

Basic Slime

  1. Mix the borax powder and warm water together. Measure out one tablespoon (15 grams) borax powder and one cup (120 ml) warm water. Add these ingredients to a large mixing bowl. Stir the mixture until the borax is completely dissolved.
  2. Mix glue and water in a separate container. Add ½ cup (60 ml) of glue and ½ cup (60 ml) water to a separate mixing bowl. Stir the mixture until the two are well-combined. The consistency of the mixture should be watery.
  3. Add food coloring to the glue mixture. Choose any color food coloring you like! Green is classic, but feel free to experiment with any color. Start with a few drops of food coloring, then stir. If you want the color to be brighter, add a few more drops of the food coloring.
    • You can also separate the glue mixture evenly into smaller bowls and make each one a different color.
  4. Combine the borax mixture with the glue mixture. Dump both mixtures into a large mixing bowl. Stir them together well. You will see the slime begin to form!
    • If you chose to make smaller amounts of slime in separate containers, evenly divide the borax solution among the containers.
  5. Let the slime sit for 30 seconds. This will give the slime a chance to solidify and reach the ideal consistency.
  6. Take the slime out and have fun! It is normal to have leftover water at the end of this process. Simply remove the slime from the water and discard the water.

"Living” Slime

  1. Mix ¾ cup (90 grams) cornstarch with 2 cups (240 ml) vegetable oil. Add both ingredients to a large bowl. Stir them together thoroughly.[1]
  2. Put the mixture in the refrigerator. Place the bowl in the refrigerator and leave it there until the mixture is fully chilled (about one hour). The cold temperature will help the slime solidify and reach the ideal consistency.[1]
  3. 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. Find a block of styrofoam. It can really be any size but the standard size is 1x6x6 inches (25x150x150mm). Run the styrofoam on your hair or on your carpet several times to give it a static charge.[1]
  5. Pour the slime mixture out slowly into another container. Place the piece of styrofoam just in front of the slime before you start pouring. It should be about 1 inch (25 mm) away from the flow of slime. The static electricity will cause the slime to stop flowing and appear to take on a life of its own.[1]
    • Wiggle the styrofoam around and the slime should follow it. Your kids will be amazed!

Edible Slime

  1. Pour a can of sweetened condensed milk into a pan. Place the pan on your stove top. Add one tablespoon (15 grams) of cornstarch to the milk and stir until the ingredients are well-combined.[2]
  2. Heat the mixture over low heat. Set your burner to low and continue to stir the mixture constantly as it heats up. If you don’t stir continuously, the mixture may stick to your pan.[2]
  3. Remove the mixture from the heat when it has thickened. As it heats up, the slime will become more gelatinous and harder to stir. Once it reaches that point, remove the pan from the heat.[2]
  4. Add 10 to 15 drops of food coloring to the mixture. You can choose any color that you want! Green is always a classic, but experiment or allow your kids to pick a color.[2]
  5. Allow the mixture to cool. Before you let your kids play with (and eat) it, let it cool down completely. The slime may stain surfaces, so make sure it's kept away from anything that stains easily or that you want to keep unstained, especially light colored objects.[2]

Soap Flake Slime

  1. Mix 1 cup (120 grams) soap flakes with 4 cups (480 ml) hot water. Measure out the soap flakes and place them in a large bowl. Carefully add the hot water to the container. Stir thoroughly until the flakes fully dissolve.
  2. Add a few drops of food coloring (if desired). Food coloring is optional, but it may make the slime more fun!
  3. Let the mixture stand for up to an hour. This will allow the mixture to reach the desired consistency.
  4. Beat the mixture vigorously with a spoon. It will begin to froth up as you beat it. It has reached the right consistency when it pours easily and becomes extremely slimy to touch.
  5. Keep the slime in an airtight container. This slime keeps very well in an airtight container. Make sure you store it away from direct sunlight and heat.

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

Tips

  • Don't put slime on carpet. It will stick.
  • Keep the slime away from pets and very small children.
  • Try pouring the borax solution slowly into the glue mixture while mixing it with a spoon. When it is very gooey, try kneading it with your hands. It will start turning into proper slime.
  • For a good and easy way to make slime, just add glue, laundry detergent, and some food coloring, and mix it up.
  • Make sure your kids don't get the slime on certain things (ceiling, walls, carpet, furniture, etc.).
  • If you don't want to use borax, try using corn starch.
  • Make sure all the ingredients are well dissolved.
  • If you put it in a cup and press down on it, the slime makes a funny sound.
  • You can add essential oils or scented liquid soap to the slime to make it smell nice.
  • Just mixing glue and food coloring by themselves, and then adding the borax and water works the best..
  • If you add color to the slime, it may stain things.
  • Wash your hands after playing with the borax slime.
  • When you add food coloring, make sure you mix it well or it could cause a different reaction.
  • The recipe can be modified by varying the proportions of ingredients. For example, if 2 parts borax solution are used, the slime that forms is "harder" and less gooey.
  • The more lotion you add the more stretchy it will become, but be careful because the lotion also makes the slime very sticky.
  • When you put food coloring in it, make sure you don't get it on yourself.
  • 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.
  • When you make slime with glue and detergent add shaving cream or foaming hand soap.
  • Elmer's glue is one suitable brand of glue. It is more generally known as poly(vinyl acetate).
  • 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.

Warnings

  • 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. If you didn't know.
