A popular park or backyard activity is slacklining. A slackline is a three-inch-wide tightrope made from seatbelt material and stretched between two trees in a park. It’s temporary and portable. Slacklining looks easy, but it’s deceivingly difficult. Borrow or buy a slackline, and if space outdoors allows, give the students a chance to try it. Compare the thin slackline to the thin feeling we experience when we wait. The faith building comes when you add the supportive layer four or five feet higher than the slackline you walk on. The supportive slackline allows for handles and ropes to hold on to while the walker crosses the thin slackline below. You can see pictures of the slackline and the supports here: https://slacklineindustries.com.
