How ball pen ink is made?
Inks. Ballpoint pen ink is normally a paste containing around 25 to 40 percent dye. The dyes are suspended in a mixture of solvents and fatty acids.
The most common of the solvents are benzyl alcohol or phenoxyethanol, which mix with the dyes and oils to create a smooth paste that dries quickly.

Why we Sneeze?ЁЯдзЁЯШк
When the inside of your nose gets a tickle, a message is sent to a special part of your brain called the sneeze center.
The sneeze center then sends a message to all the muscles that have to work together to create the amazingly complicated process that we call the sneeze.
Our eyelids shut down as part of that reaction, but it’s one of scienceтАЩs big mysteries as to why.
We think it is an involuntary response, a reflex, like when our leg jerks after being tapped on the knee.
What could be causing it? You may shut our eyelids so that when we sneeze out germs they donтАЩt fall on our eyes. Or maybe our eyes shut because they are one of a series of muscles that tighten during that involuntary response.
