Option 1: Wave Maker & Anchor Person
The Wave Maker holds the ends of the tubes securely and starts to transversely flutter both tubes simultaneously on a horizontal plane - side-to-side. Both tubes follow each other closely, but do not touch each other during this method.
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 Crossfire method as described above. Timing and communication are key.
