How a sub really works

[Lt. Commander Joe Delano]

Hi everyone, if you ever wondered how an submarine really works than take a look at this http://www.youtube.com/watch?v=Yh8rLrQyCkM It is quite technical but at least you have an idea what is going on while operating your sub.

To understand how a sub really works you will need:
one plastic bottle, one rubber pipe, a basin/tube, sth sharp, water, a marker
1.name your sub by writing her name on the bottle.
2.make three holes in the bottle. (make sure one of them is a bit smaller than the tip of the pipe.
3.put the pipe into one of the holes.
4.pour water into the basin/tube
5.put the bottle horizontally, push it downwards so that water gets into the bottle.
6.put the other end of the pipe in your mouth.
7.blow (no, not your girlfriend/wife, blow into the pipe, dumbass) to surface.
8.profit?

I'm trying that in a pool one of these days. :rock:

Of course there's the much easier way to learn about this.

Lay on your back and float in the water. Let out all of your air and you'll sink. :up:

Combine this with snorkeling and you're a human submarine. It's pretty fun. :har:

I tried that once. I then found I had no compressed air to blow ballast, and I drowned.

I have run into that problem....I end up having to order ahead flank and full rise on the planes and a little effort.

I resurface.

:arrgh!: I even did this today in a pool at the university. :har:

Never had that problem. I had plenty of compressed gas, but it all vented out in bubbles. :oops:
