USA when launched man into moon, they were not able to write with pen. Since ink will not flow in low gravity. So they spent much time and 12 million Dollar to find a pen which would write at low gravity and even on crystals.
But what Russia did in this case was they simply used pencil.
Moral : Life is so simple. Don't Complicate it.
