Jump and fling yourself against this crazy inflated wall. Wall is covered with Velcro, and participants wear a Velcro Coated suit. When the two meet, they stick and the participant then hangs there in whatever position they end up in. Participants usually have to be peeled off the wall by the attendant, then they fall onto the inflated mattress. Gets laughs from participants and bystanders alike. As seen on “Late Night with David Letterman”.
