After a few ‘lab experiments’ with static breath holding, the acid test was to get into deep water and see if it really worked. One small problem though…Dallas had never been freediving before.

So just how far did Dallas dive? And did he prove the theory?? There’s only one way to find out – keep an eye out for the new series in early 2010!
