    Right or Wrong i refill my cylinders. I have been doing this for over 20 year. I put the little cylinders in the freezer to increase the volume they will take. If you dont you may only get 9 or 10 ounces in. I also store them with metal threaded caps which seal any possible leakage. Empty or full they have caps on them. I switch to a propane tree 2 years ago so i dont use very many any more. I keep 2 in the pop just in case. Gary

    Probability vs. Cost benefit incl. effort to refill.

    I my case, I didn't realize the valve issue was an issue, but did wonder why they won't maintain their fill wt. after re-filling.

    size matters [LOL]

    the bigger the container the farther it needs to be away from me [;)]

    Those are cool!!!!
    I think the disposable ones should be outlawed....Just doesn't make sense to spend so much material and energy (production) for something that contains so little propane.

    I'm going to try to find these.

    I agree with that. I have seen the results of a 20# propane tank blowing up (on the back of a sailboat). The damage destroyed the boat it was on and damages half a dozen others. I have had the bottom of one blow out on me, freezing my tennis shoes to the ground and creating an instant sheet of ice. (was about 90% full when it failed).

    Still, glad my PUP has one.

    Be sure and get the special refill hose/valve and a fork lift (liquid delivery) cylinder so you can refill em, and what ever training that is required. or use the mac adapter [:D]

    Will we ever see these in exchange bins when we are forced to mow and weedeat with propane?

    me too and glad I have disposables bottles when needed for the lantern, tiki torch, buddy heater in deer blind and ...

    I'll just refil the disopsable ones. I have wondered about the metal caps (weather or not they work) and as someone mentioned above. They do. 4 caps, 4 refilled bottles, I'm set.

    The tankes in that video are very large. Probably O2 or something like that not propane tanks.

    Correct. O2 is not flammable. Cracks me up when people think otherwise. I always tell them to try writing a combustion equation around O2 and let me know how that works out.

    Tank explosions/fires are typically referred to as a BLEV (pronounced BLEH-Vee)

    This means Boiling Liquid Expanding Vapor.

    Heat causes the liquid to evaporate into a gas, as more and more gas builds the internal pressure of the tank increases. Eventually the tank ruptures and the gas escapes.

    Can pure oxygen "Burn", no, but neither can any other pure element.

    Oxygen is the catalyst of "Burning". In fact many of the most powerful earthly reactions use pure oxygen such as those that power spaceflight.

    Oxidizers are chemicals with free oxygen as part of their chemical make-up. For example Nitrous Oxide, which is used to increase the amount of oxygen available in the combustion of gasoline for internal combustion engines.

    Oxygen itself is Highly reactive when in contact with other materials. Hydrogen, Carbon, etc will readily react in the presence of it. You may have heard of the results of these reactions....

    H2O, Yes, Water is the ashes of Hydrogen burning in the presence of Oxygen.

    The one I ordered from eBay just came in the mail today along with 2 packs of brass caps. Can't wait to use it.

    Wow! Really?! The portal is a great place to learn about PUPs, but not so much about chemistry. [V]

    There are several elements that are flammable and around which you can write a combustion equation. Combustion is the combination of a substance with oxygen that releases heat and, usually, light.

    2H2 + O2 -> 2H2O
    C + O2 -> CO2
    2C + O2 -> 2CO
    2Na + O2 -> Na2O2

    Magnesium, potassium, phosphorous, sulphur, etc. These are all "pure elements" around which a combustion equation can be written.

    However, oxygen doesn't burn. There is no combustion equation for oxygen. This is only relevant because a person above opined that the highly flammable tank might be oxygen. Nope.

    I was speaking in terms of a single element. Not a combination of the elements. Although I suppose fission or fusion could count.
