most people likely don't understand sweat cools you down either they probably think it makes you hotter
Does blowing....on freshly written marker pen text make it dry quicker?

It's not so ridiculous a question.
You feel cool in the wind because it increases evaporation and the energy for evaporation comes from your body. Blowing on something is increasing evaporation, and so in the pen example drying your marker pen ink faster.
Why does increased airflow increase evaporation though? It's just to do with relative humidity: http://van.physics.illinois.edu/qa/listing.php?id=1471 and literally 'fresh' air. As you'd expect I guess (really humid weather is far harder to cool down in without air-con), but not entirely obvious and not really worth mocking somebody for asking.

The change in environment (when applying glue or a pen or say nail polish) such as when the substance leaving the container has a reaction. I assumed blowing increases the reaction by stimulating it and dispersing particles, thus drying faster..
annoying is when a post vanishes and you have no idea why, I would prefer an infraction and a valid reason.
AFAIK nothing anyone did in this thread is against the rules only your opinion of what should be posted in a thread?
someone made a rather bizarre observation a lot of what you deleted were other bizarre observations.
like blowing on a mirror catches the moisture of your breath. (almost the opposite some people might expect seeing as you can blow on things to dry them so was it really off topic)
I thought maybe my post had been deleted because I included and if your ginger it catches your soul , or maybe someone had thought we were intending to insult the ops intelligence which I doubt was anyone's real intention
but at least I know why it has disappeared now
