Good morning. I'm David Greene. Yesterday we reported on people throwing sliced cheese at their babies and filming it. Well, today's throwing things update is throwing Vans sneakers across the room and filming it. The purpose is to prove or disprove the theory that Vans always land faceup. People have posted videos with reactions like, this is crazy, perfect landing. Guy named Chris tweeted, I had to explain to my mom why I was throwing all my Vans on the floor at 12 a.m. Yeah, Chris, why? Transcript provided by NPR, Copyright NPR.
