Second, this video from Seth Frase, check out his vimeo channel for more goodness, but, this video is basically four minutes of waterski crash porn. Its phenomenal.
Now, if we could figure out how to make a gif, the third air chair crash would play on a loop for eternity, maybe should be on redesigned $100 bill. Its at the 2:40 mark. But, don't skip ahead. You will miss all the fun!
Also, is it called an Air Chair or a Sky Ski, i can never remember which is which.
