Don’t eat that! But wait this slime is OK if a nibble happens! We know some kids are forever going to taste things and some kids are too young to know not to taste everything. Yet, you still want to make some cool slime or putty with them. Bring on the marshmallow edible slime recipe that doubles as a cool putty idea too. Homemade slime is the best.

MARSHMALLOW EDIBLE SLIME RECIPE & PUTTY FOR KIDS!

Taste safe or edible slimes are not something we do a whole lot of but sometimes you just need an alternative to the classic slime recipes that use liquid starch, saline solution, or borax powder.

This taste safe or marshmallow edible slime recipe is perfect for the kid who has to taste everything even when he or she really shouldn’t be tasting something, like our regular slimes! But that’s ok because this slime can be tasted!

I hate to use the word edible because it implies that you should eat it and I am pretty sure this isn’t the healthiest thing to consume. However we are talking about safety, so this edible slime is perfectly fine if a little is consumed.

You can try these other taste safe/edible  options for slime too:

NEW! Gummy Bear Slime and Jello Slime

Make Fake Snot Slime

Make Edible Gelatin Slime

Make Taste Safe Fiber Slime

Make Peeps Slime

Now this marshmallow edible slime is not as oozy as our normal slimes, but it is stretchy and squeezable! Plus it smells good too. I would say that this also makes a good thinking putty or therapeutic style putty alternative. You can see our original thinking putty recipe here.

We did make a batch of blue marshmallow slime that you see above and way down below. We swirled it with our original batch of marshmallow slime too!

This edible slime recipe even has a little science to it because of the marshmallows! Have you ever noticed what happens when you put marshmallows in the microwave? They get big and puffy {before they burn if you let them go to long}!

WHAT’S THE SCIENCE IN OUR MARSHMALLOW EDIBLE SLIME?

So now we know that since this marshmallow slime is taste safe that means there isn’t the traditional chemicals involved that form the slime. So how can we make this stretchy marshmallow edible slime?

When you heat up a marshmallow, you heat up the molecules in the water that is contained within the marshmallow. These molecules move farther apart. This gives us the squishiness that we are looking for to mix up your Rice Krispy squares or our slime! The added oil does assist in the stretchiness, pliability, and general non drying of the material.

What happens between the heat and water in the marshmallow is called a chemical reaction. When you add the cornstarch, a natural thickener, you make a thick stretchy substance which is known as the great marshmallow slime! Your hands playing, kneading, stretching, and generally having fun with the slime putty keeps it going.

After awhile as the edible slime cools down, it’s going to harden. The molecules in the water move closer together again, and that’s that. This slime is not going to last all day or overnight. Yes, we put it in a plastic bin to see.

Our traditional slime does last for quite awhile, but we are dealing with candy here! We all know that cooking and baking in the kitchen is science anyway.

 

LET’S MAKE MARSHMALLOW EDIBLE SLIME!

SUPPLIES

6 Jumbo Marshmallows {make a jumbo marshmallow catapult too!}

1 TBL Cooking Oil

1/2- 1 TBL Cornstarch Powder

Bowl and Spoon

Microwave

Food Coloring {optional}

TO MAKE MARSHMALLOW EDIBLE SLIME:

STEP 1: Put 6 marshmallows in a microwave safe bowl.

STEP 2: Pour 1 TBL of oil into bowl.

STEP 3: Microwave on high for 30 secs. We have a 1200 watt microwave oven so your time may vary slightly.

Adult supervision recommend from this point on!

STEP 4: Add 1/2 tablespoon of cornstarch to heated marshmallows and mix!

STEP 5: This mixture will be hot so please be very careful!  Eventually as it cools, you are going to want to start kneading it and playing with it.

You may want to mix in another 1/2 tablespoon of cornstarch to thicken a little more. The more cornstarch you add, the stiffer it will get and be more like a putty!

Above, jumbo marshmallows and oil added to bowl. Below, marshmallows being microwaved and some very puffy but VERY HOT marshmallows!

Adding cornstarch to hot marshmallow and below stirring up the mixture. BE CAREFUL, this marshmallow slime can get hot!

The cornstarch will help the marshmallow thicken and form a slime like substance.

 

Stretch it, squeeze it, swish it, and pull it! This candy slime recipe is also awesome for tactile {touch} sensory play and olfactory {smell} sensory play!

Kids will love the way it feels and smells. Read more about tactile sensory play here for more great ideas. We have a ton of great sensory play recipes to try out at home like cloud dough and sand foam!

We like the traditional white marshmallow edible slime, but maybe you want to add some color! So, you might already know that water and oil don’t mix well together {see this fun science demonstration of that here}.

The water based food coloring has a bit of a rough start mixing with the hot marshmallow mixture but eventually it all works out! It just needs some kneading. Again, the marshmallow mixture gets hot!

We swirled our blue marshmallow slime with our white marshmallow slime just for fun!

Take science into the kitchen with your kids. This is a neat slime science activity to try with a bag of leftover {slowly going stale} marshmallows you have tucked away in the pantry.

 

I certainly don’t blame anyone if they have to take a nibble! It’s good to mix things up and try new things once in awhile. You could also check out this neat marshmallow science activity too.
