Erm...will you have a tank? Or do you want to have to strip off your weights when you realise your lungs have given out?

Put sand in your pockets until you sink. However much it takes, you need that much. If you float you are a witch.

Even with a very long snorkel, you won't be able to use it at that depth, you inspiration muscles won't be strong enough.

Try tying a 20kg plate securely to your torso, and you'll be able to stay down as long as you want. (Although as suggested, 4 - 6 kg should do nicely.)

Are you running Scuba gear?

If not, don't suggest you try at all.

If people like you ruled the world we'd of never left our caves!...

OP, "he who dares, wins!"...get the garden hose out, take off the ends, instant breathing pipe! add 4-6kg's and off you go!

...best keep a friend on the side of the pool to spot you though!

Hard to tell if that was a serious suggestion or not, but if it was, it's so far off it's not even wrong!

bks would your lung collapse at 8'6"

Pearl divers used to go to depths of 100ft without assistance. I wouldn't suggest you try that but if you just need to pick something up or unblock a filter then I don't think you'd come to much harm if you're in reasonably good shape.

I accept no responsibility for the consequences if this turns out to be wrong

The problem with a long snorkel is that most of the air that you're breathing in is coming from the pipe rather than from the atmosphere. If the volume of the snorkel pipe is more than a certain proportion of the volume of your lungs, you wont get enough fresh air and hence wont get enough oxygen.

I also don't think your diaphragm muscles would be strong enough to breath in under that pressure anyway.

Nah. All good divers have a giraffe to climb up/down swimming pools!




Seen here the diver is at the bottom doing a little job.

I shall be using a releasable knot with the weights and will not attempt this endevour without a buddy.
Cheers Mark and louibaby for the weight neccessary.

The point of this is that it takes (for me) about a third of my lung capacity just to get down theresmile I want to maximise the usable time for the task at hand.
