Hey just a quick question. I was wondering if it is possible to make a mod where when a player throws an item into a cauldron full of water it would change colors and after a couple of items are thrown in they disappear and change the color of the water. Then a player can scoop the potion out of the cauldron with empty bottles and They would receive a random potion. I do have java experience and just started making mods with forge and was wondering if this was possible.
