For those of you who don’t know this is from Wikipedia on Slacklining:
Slacklining is the use of a form of webbing that is tensioned between two anchor points to balance. Slacklining is similar to slack rope walking and tightrope walking as the line is held under tension. Slacklining differs from either tightwires or tightropes in that it is only tensioned to a point that creates a more dynamic line which has a degree of stretch and bounce making like a long and narrow trampoline. The line’s tension can be adjusted to suit the user, and different types of webbing can be used to achieve a variety of tricks. The line itself is flat, due to the nature of webbing. Slacklining has quickly become popular due to its simplicity and versatility and its ability to be practiced in a variety of environments
