Updated: November 24, 2019 Slime is always popular with the kids and the reason is simple––because it's a lot of fun! It is cheap and easy to make at home, and can even be made by younger kids with the right care and supervision. As well as being fun, it's a tactile way to relieve stress. Pick one of the four ways below to make slime, each one different to match your time availability and budget.

Making Basic Slime

  1. Mix the borax powder and warm water together. Measure out 4 tablespoons (59 ml) borax powder and 1 cup (240 ml) warm water. Add these ingredients to a large mixing bowl. Stir the mixture until the borax is completely dissolved.
  2. Add 2 cups (470 ml) of water and 1 cup of glue to a separate mixing bowl.
  3. Add food coloring to the glue mixture (optional). Choose any color food coloring you like! 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. If you add a lot, the color may end up pretty dark and when you play with it, the color will dye your hands.
    • You can also separate the glue mixture evenly into smaller bowls and make each one a different color, then mix them together.
  4. Combine the two mixtures. Dump the borax mixture slowly and a small bit at a time, because if you add too much, your slime will be hard and rip not stretch! Stir them together until it becomes your desired consistency, and doesn't stick to your hand. 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.
    • Start kneading the slime with your hands at this point. It might be sticky, but keep mixing. Add more activator (borax) if needed.
  5. Take the slime out and have fun! If it is too sticky, add more of the borax and water mixture until it gets to a texture that you like.

Making “Living” Slime

  1. Mix ⁄4 cup (180 ml) cornstarch with 2 cups (470 ml) vegetable oil. Add both ingredients to a large bowl. Stir them together thoroughly.
  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.
  3. Remove the mixture from the refrigerator. Stir it well (as the ingredients will have separated again). Let the mixture warm up just enough so 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.
  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.
    • Wiggle the styrofoam around and the slime should follow it. Your kids will be amazed!

Making Edible Slime

  1. Pour a can of sweetened condensed milk into a pan. Place the pan on your stove top. Add 1 tablespoon (15 ml) of cornstarch to the milk and stir until the ingredients are well-combined.
  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.
  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.
  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.
  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.

Making Soap Flake Slime

  1. Mix 1 cup (240 ml) soap flakes with 4 cups (950 ml) hot water. Carefully add the hot water to a large bowl. Measure out the soap flakes and place them into 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.


  • If you're keen to make a glittery or many-colored slime, see How to Make Unicorn Slime.
  • When you put food coloring in the slime mix, take care to avoid getting it on yourself. Mix it well.
  • Don’t have food coloring? Use watercolor paints or marker for color!
  • If you add shaving cream it, it makes the slime "fluffy".
  • If you don’t want to use borax you can use liquid starch, aka “sta-flo” it’s safe and clear. It is also very cheap (about $3) and you can get it at family dollar and Walmart.
  • If you make any sort of slime (holo, fluffy, crunchy etc.), always put it in a container so it doesn't dry out.
  • Don’t use too much borax solution. This will make the slime turn rubbery and it will tear easily.
  • When choosing your glue, make sure that it is a PVA-based glue.
  • If you don't want to use the borax solution to activate the slime, adding baking soda and contact lens or eye drops are a good substitute. Just make sure the contact lens solution or the eye drops have boric acid in the ingredients list or else it won't work.
  • You can add essential oils or scented liquid soap to the slime to make it smell nice.
  • 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.
  • If you are making your slime with detergent, be sure to use non-organic detergent.
  • After you make your slime, do not put it on any fabric or carpet and let it dry. Otherwise, it can stain the fabric.
  • Don't add too much food coloring as it can get all over your hands and clothes.
  • If you have sensitive skin, you might not want to use borax as it can cause burns and irritation.
  • Lotion can also make it more stretchy if the slime is thick and hard to stretch. The more lotion you add, the more stretchy it will become. Just be careful because the lotion also makes the slime very sticky. Add a little at a time.
  • 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.
  • Add contact lens solution to make your slime less sticky.
  • If the slime gets on your clothes, you can wash them. The slime should come off easily.
  • Elmer's glue is one suitable brand of glue. It is more generally known as polyvinyl acetate.
  • If your slime is too tough, add drops of glycerin to make it softer.
  • If your slime is sticky add more borax and water into it.
  • When you are done playing with your slime, put it in a container or bag and store at room temperature.
  • If you need to clean slime off clothing, furniture, carpet, etc., check out wikiHow's article for help: How to Clean Slime.
  • You can use contact lens solution mixed with a pinch of bicarbonate or soda (but only add a little bit) and mix it in. If you add paint for colour be aware; it will come out the pot watery after letting it sit, but it still makes slime.
  • Make sure to wash your hands after touching slime with borax.


  • Make sure your kids don't get the slime on areas where it'll stain or damage the surface (ceiling, walls, carpet, furniture, etc.).
  • Keep the slime away from pets and very small children.
  • Do not consume any slime or slime ingredients unless it is edible slime.
  • Don't add too much borax, as the slime will turn into a clump.
  • Borax is a detergent that can cause 1st, 2nd, and/or 3rd-degree burns. Wear gloves or gloves and safety goggles, and exercise caution when handling borax.
  • If you add color to the slime, it may stain things.
