Liquid, Solid, or Gas

I saw one of those cool air cans, used to blow the dust out of keyboards, on my mom's counter. Cool. I picked it up and sprayed it on my hand, to feel the breeze.

It was oil, not air. Dammit.

Why oh why was the temp, in December, 82 degrees?

And a big shout out thank you to those who decorate their yards with Christmas lights. We are too cheap and too lazy to do so, but all those blow up Santas and fancy lights keep my child very happy on the dark commute home.

Etcetera.

Be careful with the compressed air...they now put a bittering agent in them to keep kids from huffing and if you spray it, it lingers on your keyboard and your fingers get the taste.

I love compressed air - you can spray it for a while and then cool yourself off with the can (thanks Ideal Gas Law!) - perfect for when it's over 80 degrees in December.

are you sure it was compressed air, and not a liquified gas? Compressed air does not store efficiently... since it can't be easily converted to a liquid. Most cans I've seen of "air duster" are really a CFC or some refrigerant liquid. It is the heat of vaporization that causes the can to get cold to the touch. Also, for some fun, turn the can over and spray... just don't point it at a person... could cause frostbite.

It wasn't compressed air. Didn't you read? It was ACTUAL OIL. The can didn't even say compressed air. I just saw the can and didn't bother reading it.

I am so ditzy sometimes. :)
