How to make concrete in a microwave

Brutalism but with microwaves!

You might have heard about the tool who cemented his head into a microwave. The emergency services in Wolverhampton wasted an hour getting the man’s head out. As pranks go, it was an idiotic one and we won’t say anything more than that. But it got me to thinking – could you actually make cement in a microwave? After a YouTube search, I found a how-to guide for making concrete in a microwave but not the classic grey stuff.

The video below demonstrates how to make concrete in a microwave using sand cornstarch and water. Enjoy (and don’t be a fool when you do it)!
