FCP stories for July 2015

The July stories at the main FCP site: (1) sloshing – When you walk with a cup of coffee, why does the coffee tend to slosh out of the cup? When you walk with a mug of beer, why is the sloshing much less? Other examples of sloshing are given, such as the swimming pool on a ship in rough waters, and how to use sloshing to float an initially submerged canoe. (2) Pinhole rifle sites, pinhole glasses, and pinhole selfies. (3) Turkish coffee is brewed in hot sand --- why the sand? (4) Pub trick – balancing a safety pin on the rim of any common drinking glass.
