Don’t be afraid to make the post fun or humourous. Don’t be scared to mix it up a bit with some creative spin, fictional characters debating for example, or using your other talents to make it shine, be it music, art, photography or whatever.

I may not be Tom Lehrer, but funny songs about science are STEM content.
