easiest way to make wax:
fill a pot 1/4 with water, then put a smaller pot in it.
fill the smaller pot with candles, and crayons without the wrappers.
put the whole thing on your stove, and boil the bottom pot with the smaller pot inside of it. once the wax is all liquefied and melted, turn the stove off. let it sit until the wax is solidified. knock the bottom of the smaller pot to get the wax out. stick the wax in the freezer for a few minutes.
BAM! big ass chunk of cheap wax.
