A helium shortage has been years in the making as 75 per cent of the world's helium only comes from only three sources: ExxonMobil in Wyoming, Ras Laffan Industrial City in Qatar and the National Helium Reserve in Texas, according to USA Today.  A new reserve was found in Tanzania was discovered in 2017. Helium One began drilling at the Tanzania reserve in 2018. Although helium is the second-most abundant element in the universe, Earth only has a limited supply - and the U.S National Research Council warned in 2012 that the gas could run out by 2040. The U.S. Department of Interior estimated in 2014 that the Earth only has 1,169 billion cubic feet of helium reserves left.  In fact, it’s now becoming so rare that Nobel prize-winning physicist Professor Robert Richardson of New York’s Cornell University believes that helium-filled party balloons should be on sale for $100.
