Question: how was irn bru invented?
Answer: Until now, we've all thought Irn-Bru was invented in 1901 – possibly from iron girders – by the Scottish company AG Barr. But according to Leishman's historical digging, the first Iron Brew drink (note the strange spelling of Irn) was sold in 1889 in America, by company called Maas & Waldstein.
