  1. Pour 1.25 cups (300 mL) of clear or white school glue and 1 teaspoon (6 grams) of baking soda into your bowl and mix thoroughly. Be sure to use a sturdy spoon, as your slime will stiffen throughout the process. [1]
    • Add a few drops of your favorite essential oil if you want your slime to have a nice fragrance!
  2. Mix in 3 cups (710 mL) of foam shaving cream and stir until the mixture is nice and fluffy. It will be a bit hard to stir at first, but this is normal. Then, add a few drops of food coloring to make your slime colorful . Mix until the slime is your desired shade. [2]

  3. Thoroughly mix in 2 teaspoons (9.9 mL) of contact solution until the slime begins to pull away from the bowl. As it becomes less sticky, move the slime to a flat surface and knead it with your hands until it’s smooth and pliable. If it doesn’t lose its stickiness, add a bit more contact solution. [3]
  4. Make a slight indent in the slime and begin adding in your foam beads . You’ll use about a cup in total. Fold the slime over the beads and carefully knead it until the beads are completely blended into the slime. If you want, add some glitter to make the slime even more fun. [4]
    • You can also add the beads and glitter before the contact solution if you prefer.
    • If you want to add glitter but don’t want the additional mess, try glitter glue instead.
  5. When you’re done playing with your crunchy slime, store it in an airtight container like a mason jar or a plastic bag to keep it fresh. [5]

  1. Add 0.5 cups (120 mL) of liquid school glue or school glue gel and add a few drops of food coloring, if desired. Stir until the glue and food coloring are thoroughly mixed. [6]
  2. Dissolve 1 teaspoon (about 4 grams) of borax powder into 1 cup (240 mL) of warm water to create your activator. Slowly pour some into the bowl with the glue and stir. Keep adding the activator a little bit at a time until the slime begins to form. [7]
    • If you don’t have borax, you can use baking soda and contact solution . Add ½ teaspoon (about 2.4 g) of baking soda to 0.5 cups (120 mL) of water and stir. Then, add 1 tablespoon (15 mL) of contact solution, and the slime will begin to form. [8]
  3. While the slime is still sticky, add your slushie beads . Adding them while the mixture is sticky ensures they’ll stay in the slime. [9]
    • Find the right beads by searching for slushie beads, plastic pellets, or stuffing beads online or at your local craft store. They should be clear plastic and 3-4 mm in diameter. These beads do not have to be round.
  4. Add more activator, if needed. Be careful not to add too much, as this would make the slime too stiff. Then, knead the ingredients together with your hands until the slime is no longer sticky. [10]
  5. Once you’ve made your slime, store it in an airtight container. The color will become more clear if you leave it alone for a couple of days. [11]
    • It’s important for slushie slime to be clear so you can see the beads!

How to Make Crunchy Fishbowl Slime

  1. Pour an entire 5 oz (147 mL) bottle of clear glue into a bowl. Then, add 0.5 cups (120 mL) of water and stir well to combine. To make your slime more colorful, add a few drops of food coloring and mix thoroughly. [12]
  2. If you’re using borax, mix 1 teaspoon (about 4 grams) of borax powder with 1 cup (240 mL) of warm water. Then, slowly stir the borax into the bowl of glue. Add it little by little until the slime begins to form. [13]
    • If you’re using contact solution instead of borax, first add ½ teaspoon (5.42 g) of baking soda to 0.5 cups (120 mL) of water and stir. Then, mix in 1 tablespoon (15 mL) of contact solution and stir until the slime begins to form.
    • Another common slime activator is liquid starch . After mixing your glue and water, add 0.25 cups (59 mL) of liquid starch and stir until the slime gets sticky and starts to pull away from the bowl.
  3. Adding the fishbowl beads while the slime is still sticky helps ensure the beads will stay in the slime. [14]
    • Fishbowl beads are similar to slushie beads but are larger and flatter.
  4. Add a bit more activator to make the slime stretchy and reduce stickiness. Then, knead the slime so all the ingredients mix together. The slime is ready when it’s no longer sticky. [15]
    • Just add the activator a bit at a time. If you add too much, your slime will become stiff.
  5. Store the slime in an airtight container and set it aside. Letting it sit overnight makes the slime clearer so you can see the beads more easily! When you’re done playing with your slime, return it to the airtight container so it stays fresh. [16]

  1. Get two 6 oz (175 mL) bottles of peel-off gel face mask (like the Freeman brand) and empty them into a bowl. Then, add a few drops of your favorite food coloring and mix until you achieve your desired shade. [17]
  2. Start with about 1 teaspoon (4.9 mL) of detergent and stir it into the mixture. As you stir, slowly add a bit more as needed until your slime thickens and becomes slimy. It should pull away from the sides of the bowl. [18]
  3. As you add the beads, continue to stir the mixture or begin to knead it with your hands. The slime will be sticky at first, so keep kneading until it loses its stickiness. [19]
    • Choose smaller foam beads for a crunchier texture.
  4. When you’re finished playing with your slime, put it in a container like a ziplock bag or Tupperware to keep it fresh and pliable.

      • The stickier the slime, the more beads it can hold! Add lots of beads for an extra crunchy slime.

      • If you don’t have the specific slime activator called for in the recipe, like borax, you can replace it with another one. Borax, contact solution, and liquid starch are the most common. Just be sure to check your measurements beforehand.
