we used to try just a hose down from the surface but it's limited dew to the lung capacity and out side air pressure and depth pressure so its just turns out to be a long snorkle and not diving .

Ahhh, OK? Welcome to the board in general and to the vintage section. In this section, we discuss diving and restoring old 50s, 60s and 70s dive gear.

I tried that when I was 10 and got a in lesson physics.

Attach a foot bellows pump to the end of the hose and then time your breathing to to the rate of the person pressing the pump at the surface.....8' to 10' is possible.

When I was young and stupid (I think 8 or 9) I attached my dads air compressor via a hose to a section of plastic pipe. The pipe looked like a snorkel with an extension 6" lower than the J bend and was open. The device would supply air to me at just over the pressure at depth, excess air would vent out the bottom. It actually worked well as long as the compressor supplied more air than I breathed. If I gulped air, I could have asperated water. The downside of course is the compressor was oil lubricated, so the air tasted like oil and left a coating on my mouth. Nor was it a good things for my lungs.

Put a kink in a garden hose and leaving one end on the surface/deck and then holding the kink tight go down to the bottom of the pool and stick your tongue in the end and then release the kink.

Report back if possible.

My first dives were with a foot pump and a hose jury rigged to a DESCO triangle mask dare I say it, over 35 years ago. Couldn't get deep. A little over 5 feet probably and they were short in duration, but too cool. Wish I still had that mask. They still make them. a new one is about $700.00. Low on the list though.

Grumpy,

This is actually more hazardous than you may think. The oil is not absorbed by the lungs, and if it gets into the lungs can cause lipoid pneumonia--get enough and that can be fatal. 'Just wanted to discourage others who may read this from actually trying it with an oil cooled compressor.

I think we all thought about a longer snorkel in our teen years, but as Nemrod states, the physics is pretty brutal. I was lucky, as I read Cousteau's The Silent World, and Jacques cleared up a bunch of misconceptions in the first chapters, including the long hose, as I recall.

Nemrod,

This was like when my Mom was told in grade school in Bend, Oregon to put her tongue on the swing chain and jump off--it was a painful and bloody lesson. It was cold that winter, and for those who live in the tropics, when the temperature is around zero, anything that is wet that touches a swing chain instantly freezes to it. My Mom lost a small chunk of her tongue that day. I hope everyone reads Nem's entire post.
