The Plan

There is a new movie in the sidebar (or click here) - it's quite short, in fact I think the titles are longer than the actual footage. I shot more video, but I really think you will get the idea of what was happening from the short clip.
Honestly we did not do anything to bring this on, but we were reinforcing it with laughter and taking video.
I'm positive the ability to do this well is genetic. I honed my skill with instruction from my cousin Randy - however I prefer the two palms on the mouth method (better control of air flow). My father is a master and uses no hands, just a magic, invisible elephant that squeezes under the couch (sorry I revealed your secret, Dad).
