What happens if you put marshmallow in the microwave

Marshmallows are mostly sugar and water wrapped around a bunch of air bubbles. When you cook marshmallows in your microwave oven, several things happen at once. The hot water warms the sugar, which softens a little. The hot water also warms the air bubbles. When you warm air in a closed container, the gas molecules move around faster and push harder against the walls of the container.

As the air in the bubbles warms up, the air molecules bounce around faster and faster and push harder against the bubble walls. Since the sugar walls are warm and soft, the bubbles expand, and the marshmallow puffs up. If it puffs up too much, some air bubbles burst, and the marshmallow deflates like a popped balloon. When you take the marshmallow out of the microwave and it cools off, the bubbles shrink and the sugar hardens again.

Your child should be able to make a prediction before you heat the marshmallows about the size, color, taste, and even texture of the marshmallows. The marshmallow grew bigger in size. The entire marshmallow was gooey and melted in our mouths. The marshmallow increased in size even more than the previous marshmallow. A small hole had formed at the bottom of the marshmallow.

The marshmallow dried and flattened as it cooled. The marshmallow was extremely sticky when we tried to lift the top to look inside. There was a big hole in the middle. As the marshmallow continued to cool, it got even drier and stickier and stuck to our teeth when we tried to chew it. The marshmallow continued to get bigger as we microwaved it longer. The bottom of the marshmallow started to brown. Even before it cooled down the marshmallow had dried on the outside.

We enjoyed eating the outside of the marshmallow because it was crunchy. However, parts of the inside and the bottom were burnt and bitter to eat. Five stars, baby! Love it.

Dip your spoon into some solid vegetable shortening before you stir the mixture. The shortening will make it much easier for you to stir the marshmallows without the spoon getting stuck. Repeat the microwave and stirring process until the marshmallows are melted. You might need to microwave the marshmallows at second intervals a few times before they're melted enough to be used as icing.

Remember to keep stirring the mixture rigorously before adding the bowl back to the microwave. It should be very pliable but it should not be runny.

Add any flavorings you'd like to the bowl and stir. If you want to add a bit of extra flavor to your melted marshmallow icing, simply pour in any flavorings. Use vanilla extract or food coloring.

Keep adding powdered sugar until the dough turns into a stiff ball. Store the ball in plastic wrap overnight at room temperature.
