Anything else I drop on the floor I reach down and pick it up whether it's round, square, flat whatever. Every time I drop a piece of chalk on berber carpet(my floor), tile, concrete, etc. the chalk winds up seven feet away and on the opposite side of any obstacle. For example I dropped a piece tonight and watched it go straight down, went to pick it up and it was on the far end of my 9 foot GC IV and on the other side of table leg. My friend and I finally found it and he said,, "that's physically impossible!" My table is in the basement of a two story home, and it wouldn't surprise me to drop a piece and find it in the upstairs bathroom What's up with that?
