What happens when you put a bug in microwave?

When a bug is put into a microwave oven and the microwave is turned on, several things happen almost instantaneously:

The bug's body violently heats up due to the interaction between the microwaves and the water molecules within its tissues. Water molecules in microwaves resonate with the microwave frequency and generate heat. Since bugs are mostly made up of water, the heat generated inside them is immense compared to their small size.

This sudden and intense heat causes an incredibly high internal pressure buildup within the bug's body. Imagine boiling water in a sealed container compared to an open pot; the steam would build up pressure inside the sealed container. The same concept applies to the bug's body.

The external shell or exoskeleton of the bug cannot withstand the rapidly increasing internal pressure. As the pressure becomes too intense, the exoskeleton ruptures violently.

As a result, the bug's internal body fluids, tissues, and organs are instantaneously expelled with great force through the openings created when the exoskeleton ruptures.

In short, when a bug is put into a microwave and exposed to microwaves, it effectively explodes from within due to the extreme heat and pressure generated inside its body.
