Marshmallows expand in the microwave because the heat causes the air bubbles trapped inside them to expand, making the marshmallows puff up and increase in size.

Will marshmallows expand fastier in a microwave or in a regular oven?

Marshmallows will expand faster in a microwave compared to a regular oven. This is because microwaves heat food by agitating water molecules, causing them to heat quickly and produce steam, which causes the marshmallow to puff up. In a conventional oven, the heat is transferred more slowly through the air, leading to a more gradual expansion. Therefore, if you're looking for quick expansion, a microwave is the better option.


Do marshmallows expand or dissolve when eaten?

No, marshmallows begin to break down by amylases in saliva. And, in the stomach, gastric juices further break down the sugars in marshmallows to dissolve them down. So, marshmallows don't expand, they liquify in the stomach.


What does air pressure do to marshmallows in a bottle?

When marshmallows are placed in a bottle and the air pressure is reduced (such as when a vacuum is created), the marshmallows expand. This occurs because the lower pressure allows the air trapped within the marshmallows to expand, causing them to puff up. Conversely, when normal air pressure is restored, the marshmallows will return to their original size as the air inside them is compressed. This demonstrates the relationship between air pressure and gas expansion within objects.

How does air get into a marshmallow to make it bigger?

Air does not necessarily go into marshmallows to make them expand. In fact, marshmallows are already full of air in tiny bubbles. There are two mechanisms that cause marshmallows to expand, both resulting from an imbalance in the pressure inside these bubbles compared to that of the atmosphere. The first way would be if the marshmallow is placed inside a vacuum, or any other low pressure environment. Because there is a fixed amount of air in the bubbles (from when the marshmallows were made), when the external pressure pushing against the outside of the marshmallow decreases, the air inside the marshmallow will expand so that its pressure is equal to that of its atmosphere. The other mechanism is perhaps more familiar, and that is in a microwave. What happens is that when the microwave heats the water in the marshmallow, it warms the air and the sugary goo around it. This causes the air to expand. This is like what happens when you bring balloons into a heated building during winter- the heat causes the air molecules to move faster, and bump into the sides of the container with more force, therefore pushing outward. Again the pressures inside and outside must equal each other, so the bubbles in the marshmallow expand. Furthermore, when the sugar is heated, it becomes more pliable, which allows the air to expand more easily.

Why when you put soap in the microwave for two minutes?

Putting soap in the microwave for two minutes could potentially cause the soap to expand rapidly and create a mess, as the heat can cause trapped air bubbles to expand. It is not recommended to microwave soap as it can damage the microwave and may create a safety hazard.


How can you make blue marshmallows?

What they say to do, is put a whole heap of marshmallows over the stove in a pot, and heat until it is melted.Another response:Use a Tablespoon of butter for every 2 cups of marshmallows. Melt butter in pan, reduce heat to medium low, and add several marshmallows. Stir until they begin to melt, then add a few more marshmallows. Continue stirring and adding marshmallows until all are melted.


Why does a bar of soap expand in the microwave?

A bar of soap expands in the microwave due to the heat causing the water molecules within the soap to rapidly turn into steam and expand. This creates pressure within the soap, leading to its expansion.


How can marshmallows be thawed?

Marshmallows can be thawed by placing them in the refrigerator for several hours or overnight, allowing them to gradually come to room temperature. Alternatively, they can be left at room temperature for about an hour. If you're in a hurry, you can microwave them for a few seconds at a time, but be careful not to overheat, as they can become sticky or melt.


Will a rubber bouncy ball explode if put in microwave?

Yes, a rubber bouncy ball can explode if put in a microwave. The microwave's heat can cause the air inside the ball to expand rapidly, leading to an explosion. It is not safe to microwave rubber bouncy balls.
