The Slacktivity team was invited during the sports day in Lachen Switzerland to teach slacklining and Lyell Grunberg performed a trickline show over the lake in the harbour.
“It was great to perform in front of all these people. It was quite a challenge to be able to perform tricklining over the water without falling a single time. If I fall the show is over. But everything went perfectly and I managed to do all my tricks in a 15 minute performance.”
