Matt Parker and Steve Mould are two of the best STEM educators on YouTube. They are both witty and experimental. Parker is a straight maths kind of guy but Mould goes all over the place and really scratches that experimental/DIY itch.

If you enjoy this video, I highly recommend checking out more of their channels.
