Video cameras have been attached to hula hoops, trombones, and Fijian crab lairs, but this is the first time we’ve seen one do a kickflip backside lipslide (at 1m02s in slow motion). Watch what it’s like to be pro skater Dean-Paul Denniston’s board.
Our favorite bird videos include this frenetic feeding frenzy off the South African coast, releasing an eagle back into the wilds of Kansas, and Cornell Lab of Ornithology’s stunning Birds of Paradise project.
What’s happening when a match is lit? From Answers.com:
Matches contain sulfur, glass powder, and an oxidizing agent as the components in the match head. When you strike a match, the friction due to the particles of glass powder rubbing together generates enough heat to convert some of the red phosphorous to white phosphorous, which burns in the presence of oxygen gas. The heat from the friction also causes the oxidizing agent to produce oxygen gas, igniting the small amount of white phosphorous. Once ignited, the oxygen gas fuels the flame while the rest of the sulfur catches on fire. Of course, this entire process happens in a fraction of a second.
…unless, of course, someone films it at 4000 frames per second, and then you really get to spend time with all of the macro, slow-motion details. Fascinating to watch, and a great conversation starter about fire prevention and safety tips, and using matches as tools.
A zipline, a spring, and a frozen salmon have made grabbing a bite to eat a lot more fun for the Oregon Zoo’s cougars. Zoo Keeper Michelle Schireman explains how this new device exercises their powerful apex predator skills, sometimes for more than an hour and a half.
