To make snowballs, you need a certain amount of wet snow. In areas that are super cold, and the snow is not so wet, put a little water on them or warm the snow a bit with a heater to give it some dampness. However, if you give it a lot of moisture and leave them for very long(e.g.overnight), they will turn into ice balls and become dangerous, so be sure to use the snowballs as soon as you make them.
The amount of snow that is put into the Snowball-maker will be the right amount if you line up the table edge the Snowball-maker is on with the red line. Use the back of the scoop to hit the snow and shave it to get the right height. Also, remember to remove the excess snow that collects under the Snowball-maker so that more snow can fall off easily.
Place your foot on the upper lid of the Snowball-maker and press. Do not keep your foot in one place but move it around and change the area you press to get an even ball. Continue pressing until all of the excess snow has fallen off and you begin to hear the grind of the upper lid of the Snowball-maker and the table below.
