FCP stories for November 2014

November 2014 stories at the FCP main site: (1) The traditional physics demonstration of a ball moving through a vertical loop-the-loop has graduated to real-life examples involving waterslides, motorcycles, skateboards, and cars. It has now been done by someone simply running into the loop! (2) The hula hoop toy has also graduated into beautiful dance routines and not-so-beautiful hooping with a heavy truck tire. (3) Some materials become semitransparent when wet, which has now been employed in children’s coloring books. My granddaughter Olive is using one in the photo. (4) Pub trick: somehow getting a spoon into a mug without picking either up.
