The note about hydrogen balloons makes it seem as if helium ones are somehow better. It is not so. Helium is a non-renewable resource. It's extracted by mining and it escapes into space once released into the atmosphere. Using it for silly things like balloons takes it away from science and industry forever [0]. Hydrogen may be flammable, but it can be extracted from water. So please, don't waste helium.
