Laughing Squid posted this crazy video showing a straight rod passing through a curved hole. See below for an explanation on how it works.

YouTube user Shadow posted a video of an exhibit at the Museum of Science in Valencia, Spain that captures a visually engaging geometric concept, in which the angled position and movement of a straight metal bar allow it to move untouched through a parabolic opening in a solid plastic sheet.
