A little history about helium
Have you ever seen a balloon? Chances are it was a helium balloon. Helium is lighter than most gasses, that's why helium balloons float. Pierre Janssen in 1868 studied that year's solar eclipse and saw that there was helium on the sun. In 1895, Sir William Ramsay a Scottish chemist, heard about this and conducted an experiment with a mineral containing uranium called clevite. He exposed the clevite to mineral acids and collected the gases that were produced. Then he sent a sample of these gases to two scientists, Lockyer and Sir William Crookes, who were able to identify the helium. Two Swedish chemists, Nils Langlet and Per
Theodor Cleve, independently found helium in clevite at the same time as Ramsay.

What is helium used for?
1.To fill blimps, mostly used for advertising
2.For leak detection in high vacuum systems
3.For underwater breathing masks
4.As liquefied Helium for cooling things to very low temperatures
5.Liquefied Helium for cooling detectors is used for special telescopes
which may be lofted by (helium) balloons, carried by airplanes, and placed in
orbit around the Earth
6.Helium can be used to detect leaks (small fractures) in some vessels
7.Helium is used to make rocket fuel
8.And of course in balloons

Why is helium so important?
Helium is lighter than the air we breathe in, so you can have perfect hot-air balloons, weather balloons, and... just balloons. Helium is really important because this element lets the sun and the stars shine. Without the sun every thing would die.
