"During the space race, the Americans faced with a problem. The ink from pens depended on gravity to flow and in space where there is no gravity, the pens cannot be used to make recordings. So NASA spent millions of dollars into research and finally came out with the world's first anti gravity pen.
The Russians also faced with the same problem. They used pencil."
This was a classic joke that I heard. Sometimes, low tech just gives you the best solution. Haha.
