When a team of astronauts was sent to space, they realised that the ballpoint pens they had with them were useless, as they would leak from the refill because of low pressure and lack of gravity.
The NASA scientists decided to find a solution to this problem. They formed a team of 3 scientists to work on it. One year (and $70,000) later the team presented their solution: a state of the art pen which could operate at very low pressures and even at zero gravity.
Another team of astronauts had the same problem during their journey to space. But that group immediately came up with a 0.10 cent solution. They used pencils.
