Maybe the most surprising online hit of the 21st Century is Primitive Technology, the YouTube channel and blog of an Australian man who goes into the woods and makes things the really old fashioned way: with stone and wood and a lot of determination. (You can read a much longer description of his exploits and greatest hits here.) This week, he puts The Hunger Games' Katniss Everdeen to shame by creating a bow and arrow from nothing. Well, from a small tree and some bark. The tools he used to create it, "a celt stone hatchet, a stone chisel, various stone blades and fire sticks," were created in previous videos.
