This Christmas tree is so fucking metal

The staff at Vilnius Airport in the capitol of Lithuania decided to celebrate the holidays a little differently this year — by creating a Christmas tree out of the various objects they'd confiscated from passengers. Scissors, guns, blades, lighters, and a tree-topping star made of cheese knives. Basically it looks like the set piece for a death metal band's touring holiday stage show.

In an interview, the director of the Lithuanian Airports Security and Safety Department, Vidas Kšan, said that the tree does not include any food or liquids, which comprise a large portion of their confiscated items. Instead, the airport donates these, usually sending about 7 tons of food to charity each year. If Google Translate is actually correct (which, who the hell knows), the most commonly confiscated items are gas dispensers and electroshocks. I'm guessing that means portable plastic gas canisters, and tasers—which is still kind of a weird combination, especially for an airplane. Read the rest

Watch how incredibly delicate Japanese gold leaf is made and applied
