Main Ingredients

  • 1 cup marshmallows Any type will work, but mini marshmallows are often easier to melt.
  • 1 tablespoon cornstarch Use more if you prefer a firmer consistency.
  • 1 teaspoon vegetable oil Optional, for a smoother texture.
  • food coloring Optional, to customize color.

Instructions
 

Preparation

  • Place 1 cup of marshmallows in a microwave-safe bowl.
  • Microwave on high for 30 seconds.
  • Remove and stir; if not completely melted, microwave for an additional 10-15 seconds until fluffy.

Mixing

  • Once melted, immediately add 1 tablespoon of cornstarch to the marshmallows and mix thoroughly.
  • For extra fun, add 1 teaspoon of vegetable oil and a few drops of food coloring if desired.

Cooling

  • Allow the mixture to cool for a couple of minutes until it's safe to handle.

Kneading

  • Dust your clean surface with cornstarch to avoid sticking.
  • Transfer the mixture onto the surface and knead it with your hands until smooth and stretchy.

Notes

Flavoring can be added using flavored extracts like vanilla or mint. Keep slime in an airtight container to prolong its freshness.
