Activity #204: Microwave a marshmallow

For a quick and questionably tasty science experiment, microwave a marshmallow for about a minute and enjoy the results.


Wondering what will happen? The marshmallow will puff up to four times its original size like a poofy souffle. It will be a hot gooey mess before cooling into a crispy pancake.

Expect smiles and sticky fingers.


We tried this yesterday before bed on a paper towel to keep the microwave from getting nasty. Use wax paper if you want to eat the finished product! Ours were destined for the compost bin.
