Tom Scott releases weekly videos on his Lateral channel where they talk about some question with a weird and unexpected answer, they recently released a video discussing 'why cubers nod their heads', you can view the original video here. I suspect most of my viewers will know the answer to this question but it is still very interesting to watch people who don't know about cubing discuss it. Tom Scott clearly knows a bit about how cubing competitions run but not very much. He ultimately works out the correct answer to this question in a surprisingly short period of time, this video was shorter than many other episodes of the podcast. Also credit to Tommy Cherry for the solve at the end to demonstrate it all.
