I am so happy to be back here after a break guys.. missed you all…
Many of us would have heard a fact about using a pencil instead of a pen in space. Just a go through this fact.
During the initial space flights, Russia as well as NASA discovered that biro pens didn’t work under zero gravity conditions.
To solve this problem NASA spent 6 years and $2 million in designing a pen for use in space.
But Russia used a Pencil.
This tale with its message of simplicity and thrift floats around the world in 1960’s and even made NASA to follow this idea of using a Pencil in space. But using a Pencil in space was a wrong idea. Here’s the conclusion scientists made:
- The graphite in the Pencil has a tendency to cause explosions or fire.
- A Pencil is made up of wood particles which again can be a risk of fire.
- Pencils etching are prone to severe smearing,making them fairly worthless for permanent documentation.
- Most acceptable answer from the movie “3 idiots” – If the lead breaks away it will float due to zero gravity and can enter in the nose, ears, and other body opening of the astronaut.
