Seems like some of us ice lovers have other pica as well. For me it is baking soda...I use it to brush my teeth and if I see it during the day, I must take a lick of some. I have seen people on this site mention cornstarch, but I wonder if there are any other picas out there, so I would like to take a poll.
btw, I am eating a 24-oz tumbler of snowy shaved ice which I have just processed in my Rival SnoCone maker. I could eat 6 of these a day before my teeth start to tingle...
I think I HAVE eaten Alaska!
