how something is made?? Last night I had a yucky time trying to fall asleep...and for some reason I was wondering how they make toilet paper and get it on the roll. Other times I marvel at bridges (for example San Fran's Bay Bridge) and how they build them. Skyscrapers amaze me (my Legos always eventually fell over when I was a kid). Oddly enough...fax machines & telephones. Just crazy how something can take place instantaneously, but is going through wires a bazillion miles away. Fireflys....glowing butts? What purpose does that serve and how do they glow? Those are just a few...I mean I'm not OCD about these...but just wonder sometimes. It might be the geek in me that wishes I had taken an engineering class to figure out the bridge/skyscraper thing!
