Hold the ends of the tubes securely and walk back until you feel like you're being pulled to the balls of your feet. Start to spring the length of both tubes simultaneously as if you were shaking water off your hands. It's all about rhythm - do not muscle it. The Inertia Wave method is an oscillating, spring-like up and down continuous pattern. All of the energy comes from the center of the tubes. Do not let it hit the ground. If you hear the wind sound you know you’re doing it correctly.
