John Harmon
GeorgeWell, first we should explain that Scuba is an acronym.  S-C-U-B-A.  And it stands for something.  Here's John Harmon to give us an explanation.  
Okay, my name is John Harmon and SCUBA stands for self-contained, underwater, breathing apparatus.
The self-contained, underwater, breathing apparatus or scuba equipment, allows you to stay underwater, like a fish.
Let's have John explain the specific equipment used for scuba diving.
And basically what that consists of is some equipment, which is a tank which contains air; a regulator, which actually is the apparatus that we breathe...to deliver air from the tank to our mouths and a vest which actually allows us to sink under water or float to the surface.
Oh, exactly.  Well think about it. You're going underwater. You need good equipment.  There's the air tank, the regulator, that delivers the air from the tank, and the vest for floating or sinking and, Yang Chen, don't forget about the wetsuit.  Trusting the equipment for breathing is the hardest thing for a scuba student to learn.   
Exactly!  Your life depends on it.  So, let's hear what George had to stay.   
You gotta learn to trust the equipment  and that's probably the biggest thing for students is to trust the equipment. The equipment is high performance. This is life support equipment.  
I know.  Even though he says it's high-performance, life support equipment, I would still be nervous.
Well, see the line was really long, Yang Chen.  And I wanted to try it... but you know...
Possibly.  Okay, thanks for joining us on American Cafe.  That's all the time we have for today.
