Episode 502 - Ignobel prizes ’22 - Blind dates and Mother Ducks

We celebrate the Ignobel prizes for 2022 with science that makes you laugh and then think. What connects a Fish, ducks and slipstream racing? How do mother ducks manage to keep all their ducklings in tow? Does swimming in formation help the ducks save energy? What's the best spot in the slipstream to be? We all know following in the slipstream is good, but if you're 3 or more back you can literally get pulled along. Complex fluid mechanics makes swimming in a line a way for a mother duck to pull the ducklings along. What happens physically when you find someone who is a good match? Is eye contact or heart rate a better measure of having  a 'spark' with someone new?
