## Resource

Everybody sleeps...but did you know fish do, too? In this hilarious episode of Wow in the World, Mindy and Guy Raz dive into an incredible new scientific discovery that's changing the way we think about sleep beneath the surface. From talking goldfish to underwater sleep spas, this bedtime adventure is full of surprising science, sleepy silliness, and one very cranky Guy Raz! After yet another sleepless night thanks to Mindy's late-night TV marathons, Guy is desperate for some peace and quiet. But instead of turning the volume down, Mindy comes up with the perfect solution: squeeze Guy into a giant goldfish costume and check him into the luxurious Sand Dollar Sleep Retreat & Spa! What begins as Guy's quest for a good night's sleep quickly becomes an unforgettable journey into the science of how fish sleep. Along the way, Mindy and Guy discover that fish don't just sleep—they sleep in surprisingly human-like ways! Kids and families will explore groundbreaking research from scientists at the Max Planck Institute for Biological Cybernetics, who used a self-tracking microscope and camera system to follow zebrafish around the clock. Their discoveries revealed that zebrafish—or should we say “Zzzebrafish”—experience four different stages of sleep, complete with changing eye movements, shifting brain activity, and even short daytime naps. The crew also learns why fish sleep with their eyes open, how transparent baby zebrafish helped scientists peek inside sleeping brains, and why dolphins sleep with only half their brains at a time. Packed with laugh-out-loud moments, underwater adventures, fascinating neuroscience, animal behavior, and one unforgettable sleepover gone completely bonkerballs, this episode proves that whether you live on land or under the sea, a good night…
