'Focus On Problems' & 'Focus On Solution'
When NASAbegan the launch of astronauts into space,they found out the pens wouldn't work at zero gravity(ink won't flow down to the writing surface).In order to solve this problem,it took them one decade and spent 12 million $.
They developed a pen that worked at zero gravity,upside down, underwater and in practically any surface including crystel and in a temperature range below to over 300 degree c.
