The Aeropress Coffee Maker is so famous it has its own movie and its own championships. It's made by the same guys that designed the Aerobie Frisby too!
Mr Adler began his journey in the early 1970's with a goal to improve flying discs. He improved the design, taking inspiration from the chakram—an ancient and formidable Punjabi weapon that was shaped in a ring and added a spoiler for stability. By 1984 he had done it! He had engineered fun itself. Anyway, thats what they say on the website. He also made the Aeropress and you can buy it here.
