Why do marshmallows expand in the microwave?
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.
Can you put a rock in the microwave?
Of course you can but the real question is should you put a rock in the microwave.
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.
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.

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.

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.
Why does ivory soap expand in the microwave?
Ivory soap is whipped with air during its production, creating pockets of air within the soap. When heated in the microwave, the air pockets expand rapidly, causing the soap to grow in size and creating a fun visual effect.
Why does ivory soap expand in the micorwave?
Ivory soap expands in the microwave because it has air pockets trapped inside the soap during the manufacturing process. When heated in the microwave, the air pockets heat up and expand, causing the soap to puff up and increase in size.
