Does a oxygen/gas cylinder float?
Discussion
If it was just the cylinder with atmospheric pressure gas in it then it would possibly float.
However, due to the gas in in being compressed to about 200 times the pressure of the outside atmosphere, you'll find the cylinder with this amount in will not be able to support itself.
A 24x4 inch cylinder contains about 700 litres (24 cubic foot) of oxygen.

Buoyancy is your answer. If the density of the cylinder is less than the density of water, it will float.
Although it's got oxygen/butane inside it, that's in liquid form so it has a density much greater than that of gaseous oxygen or butane although still less than water. The weight of the steel tank and the liquified gas could be enough to make the density greater than that of water.

Serious answer:
It's about the (average) density of the object. Higher density than water and it sinks. Lower density than water and it floats.
A boat is mostly air inside, so average density is low and it floats.
A gas cylender filled with compressed air will have a much higer density. Depending on the pressure of the gas this density could be higher or lower than water, with corresponding results.
(Basically by pumping more air in the size of the object [cylinder] remains constant but the mass [aka weight, sort of] increases, so the density increases until it's more dense than water, and then it sinks.)

No. Sinks like a heavy, metal thing.
Odd that.
You mean like those new fangled metal boats? Odd that.

This must surely be the answer. Also why divers wear weight belts to counter it.king hard work if it did.Famous Graham said:
