This belief has just been solved recently. I once believed that the ice cream cone was inedible. (That means not safe to eat.) It was because for a long time I have not seen anyone eat one, and never ate it in a cone! I became secretly horrified when i saw my brother eat the cone, but i didn't dare to warn him. It wasn't until I searched on the internet that the cones are made out of wafers, which are kind of like waffles. Oh nuts! They should advertise the cones as edible, so that kids like me will not get confused!
