The results of melting soap in the microwave may not be what you want
Many people believe that heating soap and putting it in a dispenser is a good way to make it liquid. But there are problems with this. The soap cools down quickly and becomes solid again. It takes a lot of work to make liquid soap properly. Microwaving a bar is not the way to do it.

The soap will simply melt very quickly and cause a big mess. You may not even realize that the liquid soap has dried and hardened again. This will cause you to spend all day scraping soap out of a melted and cooled state. You can find many liquid soap recipes online.
The dangerous trend of microwaving CDs may have been started by social media
It was a popular trend to show how to microwave CDs in social media. This is not something you want to do at home. The outside of CDs is coated with aluminum, which acts as an antenna to receive the radio waves from your microwave.

Sparks can be ignited when the CD bounces off the waves. Social media may make the melting plasma and fireworks look like a lot of fun, but they are actually very dangerous. Avoid doing this yourself and instead look at controlled experiments on the internet. You don’t need a microwave that explodes into a fireball.
