> Take a strong bucket.

> Drill four holes in the rim

> Cut a rectangular hole in the front of the bucket.

> Hot-glue a sheet of 1/4 to 1/2 inch-thick perspex on the inside of the hole.

> Put the bucket over your head. Turn it around, you plank - you need to see out the window.

> Put two lengths of string under your armpits and tie the ends to the four holes you drilled in the rim.

> Tie bricks to your feet (for safety's sake, strap them on with velcro)

> Jump in the water

The bucket will trap air, enabling you to breath underwater for an extra minute or two.

If you want to breath longer, connect a long hose to an air-compressor, and duct-tape the other end of the hose to the inside of the bucket. As long as the compressor runs, over-filling the bucket with air, you will be able to breath.
Having been a commercial diver for several years as well as a rescue diver I feel I also have to warn you guys. There is a reason SCUBA gear is not sold to uncertified people. There are risks involved with breathing underwater. Of course everyone knows what the bends is. This is where you surface too fast to allow the nitrogen proper time to reabsorb into the blood stream. But the first and most important rule of diving, be it SCUBA or commercial, is NEVER HOLD YOUR BREATH. There is a condition called an artierial gas embolism which is very nasty. This is where your lungs rupture from holding your breath on ascent, and It can even happen in a swimming pool. You do NOT want to suffer from this condition. Please be careful. Diving is as fun as can be, but there are serious risks.

Could you please say that again in flat English? I don't know how would someone dive if s/he isn't holding breath! free diving speaking.

holding your breath in SCUBA diving is bad because if you breath in under water the air is under pressure so if you go up the pressure lessens and the air expands making you lungs burst. Usually with free diving if you breath above water, dive down and come back up while still holding your breath there is no pressure change so your lungs don't burst.

But of course talk to an expert before attempting free diving

I think they mean on the way back up, after your dive, you should blow out gently as you head towards the surface.

That way, the gases expanding in your lungs can escape easily instead of doing damage by going the wrong way.

I once read a story about four men escaping from a sunken submarine at 300 feet. After they exited the submarine, with their lungs full, the inflated their life vests.(No personal breathing devices, this was World War 2). They covered the distance in a little over 3 minutes. One man held his breath and his longs exploded. What you said is very true.
Oh yeah, your plan will work by the way. That is why I posted this. If the "window" starts leaking, lean forward in the water colum and put your face down. As long as you have positive air pressure, the water will stay out or will only come up so far.
if you dont mind i would like you to look at my post, your being a professional diver i believe you could severely help me with my adventures, haha, get back, maybe at email hondasixty@aol.com

The suggestion of connecting an air compressor to the bucket will likely KILL the user. Most air compressors are oil lubricated. That will put oil in the lungs of the driver, which prevents oxygen getting to the blood. By the time the problem is figured out it may be to late, the oil stays in lungs. That is why ALL air compressors for diving are "OIL LESS" either diaphragm or ring less (Gast).

So it is real easy to die using a standard air compressor, and many have died from it.

Does a foot floor pump have oil or cause any healft risks?
