Salt-making experiment [Things I want to do during summer vacation]

What happens if you microwave soap?

Do you know what happens if you microwave a bar of soap?

A simple experiment you can try right away if you have bar soap lying around at home or in your stock: what happens when you microwave soap? Put a bar of soap in the microwave and turn it on—you’ll be amazed by the fun sight! You can still use the soap afterward, so report on how it feels to use.

You might also capture the changing shape in a video or photos as it heats in the microwave.

It’s an experiment recommended from an ecology and SDGs perspective as well.
