For many of us, quicksand was once a real fear -- it held a vise-grip on our imaginations, from childish sandbox games to grown-up anxieties about venturing into unknown lands. But these days, quicksand can't even scare an 8-year-old. In this short, we try to find out why. Producer Soren Wheeler introduces us to Dan Engber, writer and columnist for Slate, who ran across a strange fact: kids are no longer afraid of quicksand. To figure out what happened to quicksand, Dan immersed himself in research, compiled mountains of data, and met with quicksand fetishists. Dan tells Soren and Robert about his journey, and shares his theory about why the terror of his childhood seems to have lost its menacing allure. And Carlton Cuse, best-known as writer and executive producer of Lost, weighs in on whether giant pits of hero-swallowing mud might one day creep back into the spotlight. Dan Engber's data on the percentage of movies released that feature quicksand.
