This is the slackline kit that easily installs in a backyard for balancing, bouncing, or walking in mid-air. Similar to a tightrope, the slackline is a 50' nylon strap that installs above the ground. Unlike a traditional wire, its 2"-wide surface is flat, making it easier for “slackers” to grip with bare feet, and its looser tension provides a slight spring, enabling jumping and bouncing and putting more fun in the funambulism. The slackline loops securely around tree trunks at least 12" in diameter, with a heavy-duty metal ratchet to lock the line safely in place. A second 1" wide webbing installs at waist height to give kids a helping hand as they learn to balance on the line. Includes carrying bag. Ages 5 and up. (9 lbs.)
