Add the bag of marshmallows to a large microwave safe bowl and microwave for 30-sec intervals to melt. You don’t want to overheat them as they will burn!
WARNING: MARSHMALLOW WILL BE HOT!
You can also make this recipe a cup or two of marshmallows at a time.
Remove the bowl carefully from microwave using potholders as needed. Heat again if needed. Add food coloring if you want to add color to your slime (not included in the kit).
Add the cornstarch little by little to melted marshmallow mixture. This isn’t an exact science but you can add 1/4 cup at a time if you use the whole bag (you may not need all all the cornstarch included in the kit).
If you try a small batch or about a cups worth of marshmallows, you can start with a tablespoon of cornstarch. Mix the marshmallows and pcornstarch thoroughly. Repeat as needed for thickening.
Making marshmallow slime with just marshmallows and cornstarch is going to be a messy experience! You can help to reduce the stickiness with a touch of cooking oil.
Eventually, you will need to dig your hands into the bowl when the mixture has cooled sufficiently. Our tip is to coat your hands with cornstarch!
You can add some sprinkles to make crunchy slime!
No clean hands here, but it washes up easily. Finger licking good but we don’t recommend you eat it. Last, included are some tools in the kit to help you make shapes and play with the slime! Show us your creations!
