This is an invention i have heard about, and i decided to share with everyone. It is a snowball farm. How it works? Well you make an golem which is made by two snow blocks and a pumpkin on top of eachother. Anyway you make a wall around the golem so that he is standing on one block (leave a open area below so you can retrieve the snowballs). with this wall the golem will not be able to leave the one block he is on, therefore he will produce snow on the ground forever. By using a shovel you can get unlimited snowballs. HAVE FUN!!!
