Short Stuff: Pruney Skin

In this episode, Josh and guest host Jerry dive into the fascinating science behind why your fingers and toes get all wrinkly and pruney after soaking in the bathtub—spoiler alert, it's way more complicated than you'd think! They explore decades of scientific research that debunks the old osmosis explanation and reveal that your nervous system is actually shrinking your blood vessels in response to water, plus they discuss a fascinating evolutionary theory that suggests pruney fingers might actually give us better grip on wet objects. It's a quick, quirky exploration of a weird bodily phenomenon that'll make you look at your next bath time with fresh eyes.
