Charge

This past week we've been talking about charges and stuff. This made me remember this past summer when I went to Washington to look at colleges. Although it was summer, it was still a little cold. This meant that if the humidity was lower, it would have been a great place to get shocked from static electricity. Charges seem to build up better when its cold and dry like Las Vegas. I don't remember if I ever got shocked during that trip but I remember riding the plane on the way back home. Planes have lightning rods on the wings so that the charge that gets built up by friction (since the plane is in constant contact with the sky), can escape to keep the plane safe. This happens because charges like to build up at sharper points and they'll eventually fall off back into the atmosphere so the plane won't attract something like a lightning strike.
