In this bonus episode of RecSci Quick Bites, Lu and Tirth discuss more funny studies they didn’t get to talk about at length during season one. These include making knives out of poop, performing colonoscopy on yourself, reasons why babies are so small, the happiness of Olympic medalists, the worst time to consume chili, zebra-striped mannequins, and giving it to Reviewer 2.
