on a recent dive trip I forgot my snorkel at my car.... needless to say it was a long way to my car and I thought it would be fine to try and dive without my snorkel... it was so difficult... but as luck would have it there was a reason I watched hours and hours of MacGywer when i was younger! I made myself a snorkel out of some kelp...
and it worked great!
some problems is that you have to use the younger kelp to make one (because it's alot more flexible to slide and bend into your mouth!) but it can't be made out of the ends because they are to narrow making breathing and clearing really difficult... needless to say it could have been a terrible dive but I ended up really enjoy the dive and could appreciate the importance of not forgetting your snorkel!
