The easy way to do this is with liquid gases. 1 cup liquid nitrogen 2 1/2 cups liquid helium 1 1/3 cups liquid oxygen dry ice to taste shake well. Serve chilled. there no worries. Brandon

Bob, I was under the impression that those divator rigs were actually pretty popular. There are several of them collecting dust at my shop. Apparantly, they know of one guy that still uses his. The best part about mounting tanks upside down, though, is the jet-pack effect when your...

I think that LUBOLD8431 was trying to flame me, and not the deceased instructor. :rolleyes: The problem that I see is that zinc oxide fever occurs from (relatively) extensive inhalation of zinc oxide fumes and is an irritation in the lungs (see any MSDS). Zinc oxide is also used in...

So steel tanks aren't galvanized on the inside? I am going to insist on having mine done inside and out :) . I guess that's what happens when you assume. I took the time to try to look up the rate law (an equation that predicts the concentration of the components of the reaction at a...

I have been on Zoloft for several years and it has completely changed my life. I have had no adverse reactions (the side-effects for SSRIs are all about the same). The main problem is that users can be unstable until one adjusts the dosage correctly. You should have no trouble obtaining...

I was taking a break from exams and reading the DAN Incident Report (For those of you who are members, read it. For those who aren't, buy it or join DAN and read it) when I came upon an incident: They are claiming that oxidation in the tanks reduced the amount of oxygen available in the...

i was DMing a dive for some students when one of them picked up a sea cucumber (which we unfortunately told them was a donkey dung sea cucumber) and then pretend to eat it. Conveniently the anus was pointed away from his mouth when it ejected. brandon

First, adventure diver is part of AOW, so if they are telling you it's a separate certification they're leading you on. However, AOW can be a good introduction into local diving and nitrox is just good in general. About the classroom time, nitrox is rather easy and AOW doesn't really have much...

That's it, except it's 50 cu.ft. of gas. b

It's really not that bad. Just read through your workbook and maybe check out the encyclopedia. It seemed kinda basic to me. brandon

I say go with DAN just so you know that you are supporting research and a worthwhile medical consultation service. Besides, its headquarters are just down the road from the southern part of heaven (UNC). brandon

Fly N Dive, Who are you diving with in the BVI's? If you are going on ActionQuest then there is a good chance that I will be your instructor :) Btw, Diving off a sailboat is noticably more difficult than off a power boat. There is a lot more freeboard so entries and exits are more...

Doppler, What is the partial pressure effect? I have never heard that term used before. While I could understand the benefits of using pure O2 to eliminate N2 in the breathing media, I do believe that whatever get's you out of the water fast would be beneficial (which for many dives means...

Several organizations have programs for certifying experienced divers (notably ex-military divers). I don't know how common it is, but it is common enough to allow for a modified certification procedure. brandon

Please don't make me give the table speil! Tables are designed for what they are used for. Navy tables are designed for deco. RDP is not. That's why its more liberal with repetitive dives. brandon

According to PADI, for 10 and 11-year-olds the limit is 40ft with a certified parent or padi pro. For 12-15-year olds the limit is 60ft with an adult or padi pro (except for AOW deep dive, 70ft). They claim this is because it inhibits growth. However, in the next paragraph they go on to claim...

...costs far too much money. brandon starving student and dive instructor

I have it on very good authority (PADI Examiner and one of the leading course directors) that PADI is going to release a trimix course this fall or thereabouts. I wanted to know if anyone knows anything about it or has any opinions (I know you do...). Also rumor has it that the DSAT TecDeep...

the vytec is your first computer?

I like to take several shots of jaggermeister during the SI. Gets rid of the saltwater taste and keeps me warm on the next dive. The only problem is when I do repetitive bounce dives I get really wasted. Of course, I am kidding. I like the taste of saltwater in my mouth. It's freshwater...
