FACT 32: Where do they make Balloons?

I was listening to the song "Where do they make balloons?" by They Might Be Giants today and I began to wonder about balloons....so naturally I looked them up. This is what I learned:

"The balloon was invented by the Luso Brazilian priest (at 45 years of age) Bartolomeu de Gusmão (brother of the Luso Brazilian statesman Alexandre de Gusmão), and the first public exhibition was to the Portuguese Court on August 8, 1709, in the hall of the Casa da Índia in Lisbon.......The rubber balloon was invented by Michael Faraday in 1824; it was inflated with hydrogen and used in his experiments with that element.^[1] Rubber balloons were soon after sold for a penny a piece in parks and circuses in America" (wikipedia.org).

Pretty cool!
