We use things every day without ever wondering why they are the way they are, and how these inventions came to be. There are reasons why women’s bikes are different than men’s, why a beer bottle is brown instead of purple, and why most door knobs are brass. From golf balls to seatbelts we take for granted how much goes into the design of the things we use everyday. Well the answers to all those questions no one ever had the answers to have been scraped together and wrapped up into this little video. Find out who invented the Post-it note and how it was created by accident and how the paperclip evolved. The fun answers to the questions we never thought to ask.
