Thankfully this wasn’t a planning mistake – 11 of us climbed into the hyperbaric chamber at the London Diving Chamber, in St John’s Wood, for a dry dive to 50 metres.
I think it’s safe to say that all of us were ‘narked’ and this was very much expected… what was not expected is the funny squeaky voice syndrome that accompanies the experience (high-pressure affects the pitch of your vocal chords).
In the end I’m not so sure if we were laughing so much because of Nitrogen Narcosis or simply because everyone sounded hilarious!!
