Nov. 11, of course, is famous for a number of reasons. One, obviously, is that World War I ended on that date in 1918. Another, is that the party season of Carnival kicks off. Here at Spiegel Online, however, our thoughts have turned to Christmas -- and more specifically to Christmas gifts. Tops on the list so far is the gift of cleanliness. Leave it to the Japanese to come up with a table that cleans itself.  And, if you do decide to order one for your favorite slob, make sure he or she has plenty of room under the tree    -- or at least next to it. 

Smile Like You Mean It

Professor Paul Ekman, a psychologist from the University of California, has researched how adept people are at spotting a fake smile. Think you could? BBC Science has been kind enough to put a test online  consisting of 20 short video clips so you can check your people-reading skills. At the end it lets you know what to look for in the future to make sure your friends aren't just humoring your stupid jokes. SPIEGEL managed to get 17 out of 20 smiles right, which isn't so bad considering we're confronted with the German service industry on a daily basis.

Not Your Father's BBC
