SCUBA Diving, Urban Legends and Mythbusters

In the event of a first stage failure you can take the reg off a tank and sip air directly from the valve.

I haven't wanted to screw up a regulator by taking it off a tank underwater but I have swam around with just a tank, sipping from the valve without a problem. Just like drinking from a water fountain.

Tank Rodeo is pretty fun. Pinch a tank between your legs, crack the valve and let it push you around in the water.

I'm still trying to perfect the following scuba prank. Get a bunch of cylinders and put them at the bottom of a pool while the victim is on the surface talking to their students. Have some friends help open the tank valves at the same time. I'm trying to get enough air coming out so the person sinks to the bottom but all that is happening with 3 tanks so far is that the person on the surface gets pushed to the side. We're going to try 6 tanks next time.

Sorry, these aren't really myths.. just a bunch of bored people with access to lots of tanks.

My biggest issue with the the "remove faulty first stage myth" is that if it fails in such a way that it wont deliver any air (unlikely) how are you going to relieve the pressure on it in order to take it off the valve while under OOA stress in the first place?

You could do it like they do in the movies, just whip out your Bowie knife and whack the valve off in one clean stroke.

Can't. Big Bowie knife on my leg is tangled up in a bunch of kelp and I can't get to it.

Hmmm, I think that was in a James Bond movie. Might have to include the "tank scooter" in the list...

I figured someone would get a good laugh out of that!

Use your back up knife to sever that leg from your body so you can get access to your Bowie knife.

Don't forget that drinking Ice Tea at certain dive resorts will cause Decompression Symptons

That's LONG ISLAND ICED TEA.

That's LONG ISLAND ICED TEA.

Just avoid Long Island then.
