Place the marshmallows in a microwave safe bowl.

Add the olive oil.

Heat in the microwave for approximately 45 seconds to soften the marshmallows.

Then add 1 Tablespoon of the corn starch to the bowl.

Mix until well combined and the slime is confirmed. Be careful as the mixture will be hot

Once it has cooled some, sprinkle the table or mat with corn starch.  Then place the slime on the mat and sprinkle more corn starch on top of it.

Sprinkle your hands with cornstarch and then knead with your hands until the slime is formed.

Enjoy and it's edible!
