#9 – Tea Bags
Tea bags are easily one of the simplest genius ideas that are being used in huge amounts every single day, so it’s hard to imagine that they were actually discovered by accident. However, in 1908, an American entrepreneur named Thomas Sullivan decided not to send tea the traditional way to his potential customers, but to put dry tea leaves inside a little silk bag. He thought that people would open the bag and use the contents of it in a traditional way. However, the customers immediately assumed that they should dip the whole bag inside a cup filled with hot water. People figured out that this was the most convenient way to enjoy a cup of tea, and it has never been the same since. Nowadays, the tea bags are made out of filter paper.
