The Game of Hacky Sac or Footbag What if I told you that in my hand I hold the secret to world harmony that diplomats have been searching for for centerys. That a toy about the size of a plumb can improve your physical and mental well being tremendously. It may sound corny, but it may even bring you at peace with the world. You may call me crazy, but I believe that this little devise can do all these things. This is the hackysac, or footbag as it is officially known, and it is the only component necessary in a very exciting game. But to me, it is much more than a game. To me, it is an expressive dance, a natural high, an important social skill that everyone should become familiar.
