Slime is a great substance for kids to play with, but young children often put it in their mouths. To create a slime that's safe for kids to taste, use common kitchen ingredients. Cook sweetened condensed milk with cornstarch and sugar or microwave gummy bears or mini-marshmallows with oil.

    Open a 14 ounce (396 g) can of sweetened condensed milk and spoon it into a small saucepan. Stir in 1 tablespoon (12 g) of cornstarch and 2 tablespoons (25 g) of sugar.
  2. Turn the burner to medium-high and stir the slime constantly as it cooks. It should thicken slightly and become stretchy once it's cooked long enough.
    • Keep in mind that the longer you cook the slime, the closer to playdough it will become. Cook it less for a wetter slime.

  4. Turn off the burner and let the slime come to room temperature before you scoop it onto a play surface.
    • The slime may thicken a little as it cools.
  5. Once you've finished playing with the sweetened condensed milk slime, put it in an airtight container or resealable plastic bag. Store the slime in the refrigerator and use it within 5 days.

    Put 1 cup (200 g) of gummy bears into a microwave-safe bowl and heat them for 30 seconds. [8]
    • If you want your slime to be a bright color, use gummy bears that are the same color instead of a variety.
  2. Watermark wikiHow to Make Edible Slime
    Carefully stir the hot gummy bears and heat them for another 10 seconds if they haven't melted. Continue to stir and heat the gummy bears for 10 second intervals until they're smooth.
    • Stirring will also help the melted gummy bears cool once they've melted.
  3. Watermark wikiHow to Make Edible Slime
    Measure 2 tablespoons (25 g) of cornstarch and 1 tablespoon (8 g) of powdered sugar onto a large plate. Mix them until they're combined and set aside half of the mixture.
  4. Leave the gummy bear mixture until it's cool enough to touch.
  5. Watermark wikiHow to Make Edible Slime
    Use your hands to knead the gummy bears into the dry ingredients. The slime won't be as sticky once you incorporate the dry ingredients. Knead in the rest of the reserved powdered sugar and cornstarch.
  6. Watermark wikiHow to Make Edible Slime
    Pour the oil onto the gummy slime and use your hands to mix it in. You should notice the slime become stretchier.
  7. As soon as the slime is as gooey as you like, you can play with it. If it starts to harden, stick it in the microwave and heat it for 10 to 30 seconds.
    • Avoid reheating the slime more than once and don't store it because it will harden very quickly.

    Put a gummy candy in the microwave for 10-20 seconds. Try the shortest time, then zap it for a few more seconds if it doesn’t melt completely right away. Once it’s melted, stir it up with a fork, then knead it with your hands when it’s cooled down a little. It will become a gooey blob of opaque slime!

    To make a slime you can drizzle over a cake or cupcake, mix ½ cup of corn syrup and 1 tablespoon of powdered sugar with a few drops of food coloring. Green is a good bet if you want a nice “slimy” color. Drizzle the slime on with a spoon or fork.

      Article Summary X

      One way to make edible slime is to use sweetened condensed milk. Combine a 14 ounce can (415 mL) of sweetened condensed milk, 1 tablespoon of cornstarch, and 2 tablespoons of sugar into a small saucepan. Heat the pan over medium-high heat and stir the slime as it cooks for 10-15 minutes. Then, mix in 10 drops of food coloring to make your favorite color. Once the slime is thickened and stretchy, remove the slime from the heat and let it cool to room temperature.

Pour 2 tablespoons (30ml) of vegetable oil over the marshmallows, and microwave them for 10 seconds at a time until they melt. Next, stir a few drops of food coloring into the melted marshmallows to make your slime colorful. Finally, mix the melted marshmallows with 2 tablespoons each of powdered sugar and cornstarch. Enjoy.
