    Aside from the difficulties helium balloons are causing Network Rail, isn't it time a ban was put on wasting this precious resouce by filling idiotic balloons with it?

    Once its gone, it's gone and when it's gone, we won't be making MRI scanners.

    The earth generates helium as it is a radioactive decay product from isotopes in the Earths crust and magma. This then dissolves in oil deposits and is extracted from the oil when it is pumped to the surface.

    Yeah, but when you consider the alternative ideas for balloons-well...they'll never really take off.

    This is a very old but still valid video showing the properties of the Noble gases.

    True.

    However, radioactive decay of terrestrial rock accounts for all of the Earth's store of the gas. There is no way of manufacturing it artificially, and practically all of the world's reserves have been derived as a by-product from the extraction of natural gas, mostly in the giant oil- and gasfields of the American South-west, which historically have had the highest helium concentrations.

    The fact is we are using and releasing helium at a faster rate than it is being produced.

    Quote from the BBC article
    "Ideally, we'd ask people not to bring balloons into our stations at all. Alternatively, carry them in bags so the risk of them floating upwards is minimised." said the chief operating officer for Network Rail's London North Western route.

    Hmm.

    Interesting "advice" when you consider this which happened (you don't have to actually read all the links, I'm just being dramatic)

    Apart from which, the expectation that parents who have just bought their child an oversized helium balloon ought to then bag said balloon is not realistic really, much as you wouldn't get somebody to wear a balaclava whenever they just got their hair cut in an expensive and pleasing way.

    Banning them makes better sense.

    I thought they must have been serving beans or pea n 'am soup in the dining car!
