Recipe #1 – Fluffy slime

Watch our video for this fluffy fun slime recipe. It comes from our centre at Petit Early Learning Journey Forest Hill, which experimented with making Fluffy Slime for Science Week in 2021. This recipe was popular with our families who could not visit our centres at the time.

Ingredient list

To make our fluffy slime, you will need the following ingredients:

  • ½ cup of PVA school glue
  • One cup of shaving cream
  • ½ teaspoon of bicarbonate soda
  • A couple of drops of colouring (any colour you like)
  • ¼ cup of water
  • One tablespoon of saline or contact lens solution (20ml)


Step 1: Gather your materials and ingredients. To mix your solution, you will need a bowl, wooden spoon, measuring cups and spoons for the slime ingredients.

Step 2: Pour into your container half a cup of white glue. You may need your wooden spoon to get it all into the bowl.

Step 3: Add the shaving cream. You can use the same measuring cup you used for the glue.

Step 4: Add the bicarbonate soda.

Step 5: Add one-quarter cup of water.

Step 6: Pour in a couple of drops of food colouring.

Step 7: Give all these ingredients a mix.

Step 8: Then, slowly add a tablespoon of the saline solution as you continue to mix.

Step 9: Keep giving it a good mix until it thickens and stretches.

Step 10: It is time to use your hands! You can knead your slime by pulling and pushing it around until it is flexible and ready to play with.

You can store batches of slime in sealed glass jars such as repurposed coffee bottles, jam or vegemite bottles. The better the seal, or airtight container, the longer your slime will last.

Recipe #2 – Gooey glue-based regular slime

You will find variations of this recipe online that call for different measurements and processes. It provides the basis for many different types of slime, including a unicorn and rainbow slime.

Ingredient list

To make a gooey glue slime, you will need the following ingredients:

  • 1 cup of PVA children’s glue
  • ½ cup of warm water
  • Drops of food colouring (optional)
  • 1 teaspoon of baking soda
  • 1 teaspoon of contact lens solution (saline)


Step 1: In a mixing bowl, pour one cup of glue and add ½ cup of water while stirring with a wooden spoon. Mix well until the glue and water are fully combined.

Step 2: If you want to add colour to the slime, add a few drops of food colouring and stir until the mixture is consistent.

Step 3: Add one teaspoon of baking soda to the mixture. Stir vigorously until properly mixed.

Step 4: Add one teaspoon of saline solution to the glue mixture and stir thoroughly while the slime forms. The contact lens solution is the slime activator that helps the slime to form. Add it slowly and never add more than the recommended amount.

Step 5: When the slime mixture starts coming together, use your hands to knead the mixture until it becomes stretchy and pliable. If the slime is still too sticky, add a little more contact lens solution and knead again. If it’s too hard, add a little water and knead till it becomes pliable once more.

Step 6: Once you’ve achieved the right consistency, store your slime in a sealed container to maintain the right texture. Slime can last for a long time if well-packed and can make a great Christmas stocking stuffer.

Recipe #3 – Edible slime recipe with marshmallows

We tried a fun experiment with this recipe by squishing the marshmallows in our hands and adding some cooking oil and water. While it was absolutely fun, it didn’t create the right slime consistency.

For this edible marshmallow slime recipe, you can purchase a bag of marshmallows or use leftover marshmallow bunnies or eggs from Easter.

This recipe involves microwaving marshmallows. They can quickly become hot and burn. To avoid first aid for children, it should be supervised by an adult.

Ingredient list

You will need to put together the following items for edible slime:

  • 2 cups of soft marshmallows, pink, white or both!
  • ½ cup of cornflour
  • A spoonful of coconut oil. (This can be swapped for vegetable or sunflower oil)
  • Food colouring if required


Step 1: Take two cups of soft marshmallows and put them into a large microwave-safe bowl.

Step 2 Microwave the marshmallows for about 20 seconds. The timing will depend on your microwave, but you want the marshmallows to be pliable. Use a teaspoon to check their consistency. Don’t use your fingers, as the marshmallows can burn. If the marshmallows don’t have enough give, microwave again in short bursts.

Step 3: Stir your melted marshmallows together until they are almost like a liquid consistency

Step 4 Add a half teaspoon of oil to keep them moist and keep stirring.

Step 5: Slowly add the rest of the oil.

Step 6: Now it is time to add the cornflour. And like the oil, you should add and stir this in slowly. The cornflour will help keep the marshmallow slime from sticking to everything including your fingers.

Step 7: Colour your marshmallow slime or keep it naturally pink or white. Some children love to add sprinkles or chocolate buttons. Be aware the warm marshmallows may melt the buttons and make the slime super messy – but that’s all part of the fun!

Step 8: Once the marshmallows are cool enough to touch, you can use additional cornflour to coat your fingers and your children’s fingers so they help you knead, roll and stretch the edible slime.

To avoid a sticky environment, add extra cornflour to the surface where you’ll be playing with your slime.

Recipe #4 – Goop

Sometimes slime is referred to as goop (or Oobleck as it is called in Bartholomew and the Oobleck a children’s book by Dr Seuss).

And we have a basic slime recipe that is perfect for goop. It is our second suggestion for how to make slime without glue or a saline activator.

Ingredient list

  • 1 cup of warm water.
  • 2 cups of cornflour.
  • Food colouring if desired.


Step 1: Place 2 cups of cornflour in a large bowl.

Step 2: Slowly stir in the water.

Step 3: Add food colouring if desired.
