"Houston, we have a problem. Some pen turners are taking an online science quiz and now think they can be astronauts."

I got 12 out of 13. Missed the question on Nitrogen in the atmosphere. Why is that Bloxygen stuff so expensive, then?

A little pen turning humor, there.

Same.

I get a chuckle when the tire stores try and sell me nitrogen for my tires for an extra $10 per tire...no thanks, I'll take the 80 percent that's in ambient air, thanks - quite sure I don't need the extra 20 percent for $40! :)
