Always an easy way to solve a problem.It seems that at the beginning of the space race, it was discovered that ball-point pens would not work well in zero-G conditions. So, the US spent millions developing a pen tht would write underwater, on glass etc.(The Soviets used a pencil!)Can anyone confirm this?
