Option 1: Wave Maker & Anchor Person
Hold the ends of the tubes securely and slowly start to rotate your left hand counter-clockwise, and your right hand clockwise. This is circumduction; fluttering one tube under the other in an upward swiping motion. Keep your wrists loose and listen for the wind sound. Don’t let the tubes hit the ground.
Meanwhile, the Anchor Person holds the ends of the tubes on the opposite side and attempts to hold them in place.
Option 2: Wave Maker & Wave Maker
Both users are Wave Makers and simultaneously perform the Double Under method as described above. Timing and communication are key.
