With some warm water, an empty and rinsed can of beans, a candle and something to break a candle will get you started on this project.
You can buy wax flakes, but that it's nearly as enjoyable/stress-relieving/cheap as defacing an innocent vanilla candle. With a chopping board underneath and your demolishing device of choice, go nuts breaking the up the wax and saving the wick when you reach the middle.
Waxy bits all diced up and ready to be melted. Place in tin in hot water and let the melting begin.
Once it's melted to a liquid, pick your poison of tea cup, cut a wick thats long enough with at least a 1/2 inch to spare over the top of the tea cup and pour away. In order to have the wick stay above the wax, I held it up with a cloths pin on top of the tea cup. I also used chopsticks taped together for another one seen in the picture. Let it set and dry and pretty soon you'll have a candle in a tea cup.
