Was kind of fun, instructor was visibly upset at my lack of coordination so there's that. Who'd have thought that two separate minutes of attempting a fringe activity in a wind tunnel wouldn't be enough to learn the complexity or nuances that would allow me to not bounce off every wall of a plastic tube. Save your money unless you are after some unintentional comic relief.
Update my elbow still hasn't healed since "flying my body" in a tube. If stability isn't generally achievable on your first time through perhaps having an instructor that can actually prevent your body from ricocheting off the plastic cylinder would be ideal? What kind of joke is this business model to learn something new? Why don't ski slopes adopt a 45 dollar surcharge per run every time you want to fly your body down a hill?
