Featuring Peter Winkler, our SciShow graphics guru, and Professor Claw, the emperor scorpion. We decided it would be cool to have guests come into the studio and talk about science with Hank. In this episode, Peter and Hank discuss the science of prosthetic skin and Saturn's rings. Then Jessi from Animal Wonders introduces Professor Claw, the emperor scorpion and Hank debates how cool it is to get stung by a scorpion.
