Episode notes
Helium Discovery
- In 1903, prospectors in Dexter, Kansas, struck a well producing a large amount of gas, initially believed to be natural gas.
- During a celebratory lighting, the gas extinguished the flames, revealing the presence of helium.
Helium's Origin on Earth
- Earth's helium originates from the radioactive decay of elements like uranium and thorium.
- It accumulates in underground pockets, unlike the helium found in the sun.
Helium in Warfare
- During World War I, the U.S. secured helium reserves for non-flammable blimps to counter German Zeppelins.
- Though the war ended before their deployment, this marked helium's strategic importance.
