Belgian chocolatier Dominique Persoone snorts cocoa powder off his Chocolate Shooter in his factory in Bruges, February 3, 2015. When Belgian chocolatier Dominique Persoone created a chocolate-sniffing device for a Rolling Stones party in 2007, he never imagined demand would stretch much beyond the rock 'n' roll scene. But, seven years later, he has sold 25,000 of them. Inspired by a device his grandfather used to propel tobacco snuff up his nose, Persoone created a “Chocolate Shooter” to deliver a hit of Dominican Republic or Peruvian cocoa powder, mixed with mint and either ginger or raspberry.

In this photo taken Tuesday, October 14, 2014, skulls and bones are stacked at the Catacombs in Paris, France. The subterranean tunnels, stretching 2 kilometers (1.24 miles), cradle the bones of some 6 million Parisians from centuries past and once gave refuge to smugglers. The site used to close at 5 p.m., but is now staying open until 8 p.m. The change is mainly aimed at allowing more people to visit and reducing long lines, since it can only hold a limited number of people at a time and visits can't be reserved in advance.
