Hi ... Found a Bug: I made 64 wooden Bowls (Which stacked) and i went down to my mushroom cows to fill them with soup to stok my shop. I clicked on the Cow with bowls in hand and it replaced my 64 bowls with 1 mushroom soup .
It's a minecraft bug, as Notch didn't really think ahead to notice that Mushroom Soup is the only non-stackable food and that by filling up something stackable and making in non-stackable, you would remove all the excess. Same thing happens when you fill up a stack of buckets.
Also i must add for anyone else out there this Also Effects Glass Bottles (For Potions) When filling them with water
