Helium has an interesting history; during the nineteenth century, one of the things some scientists declared to be "impossible"<ref>[http://www.astrophysical.org/astrophysics.php Astrophysical.org]</ref> was the determination of the chemical makeup of the stars. Then spectroscopy was developed, and the composition of the stars became known in great detail. Helium, in particular, was discovered in the Sun (as an unknown element) ''before'' it was discovered on the Earth. It was, accordingly, named after ''Helios,'' the Greek god of the Sun. It was first found in natural gas in 1905 at the [[University of Kansas]]. <ref>http://www.news.ku.edu/2000/00N/AprNews/Apr7/bailey.html</ref>.

Helium is the only inert gas that floats in air this is because it has a negative mass. It commonly used to make balloons float and works when you add more helium to the inside of the balloon than there is material making up the balloon. Although this may seem like magic or witchcraft it is harmless and fun. It should never be confused with soul sucking hot air balloons which are suspended by the delves angels.
