Stone Skipping the Scientific Way

Quirk writes "National Geographic has a bit on the scientific analysis of stone skipping. Using a machine launching aluminum disks Lyderic Bocquet, a physics professor at the University of Lyon, and his colleagues discovered the 'magic angle' of 20 degrees as that required to maximize skipping. 'Jerdone Coleman McGhee of Wimberley, Texas, holds the current Guinness Book of World Records title for a 1992 toss that yielded an impressive 38 bounces across the Blanco River in central Texas'"

      I had a friend that used to see how high he could hock loogies into the air and then catch them with his mouth.

      It grossed me out then and 20+ years later it still grosses me out. Just thought I'd share :)

      I had a friend in highschool that had a perpetual sinus infection. He could hawk up a seemingly unlimited amount of the ugliest green mucous Iv'e ever seen. I mean, this shit was worse than the stuff they used in Aliens.

      He'd go outside, and spit on the wall of the school. At the end of the year, it was absolutely covered by dried up slime. I can only imagine that they could have removed it with a sand-blasting pressure-washer.

      Being the king of mucous, he'd spit it up in the air, as your friend did, and catch it, but the wall trick was by-far the worst.

  6. 20 degrees the best angle? by Aardpig · · Score: -1, Offtopic

    In honour of the nationality of the scientist involved in the study, and to counter any anti-French sentiment which may have arisen due to unfortunate recent events on the geopolitical scene, maybe we need a new unit for angular measurements: 20 degrees = 1 degree of freedom.

    I was disappointed by the lack of pictures in the article, so I went hunting at one of the researchers' sites. Couldn't find the stone skipping machine, but I found a cool movie of a skipping stone. My dad and I used to do this stuff up in Michigan, it's nice to learn the physics behind it!
