The kids made these tonight at our 4-H meeting and then brought them home to finish them after they were completely cooled. This project is a great way to use up old odd and ends of candles.
Using a single serve milk carton, spray the inside with cooking spray. Tie the wick on to a pencil and hang it over the very middle of the carton. Fill the carton with ice chips to the top. Ever so careful pour melted wax into the carton. Let this sit until the candle is cool and hard. Carefully peel the carton off the candle, do this over a sink or outside because now all the water from the ice will run out. If the candle breaks, which it may at this point, just remelt the wax and try again. The ice at the top of the carton melted with the hot wax but by the time it gets to the middle and bottom it is cool enough not to melt the ice and you get this really intricate candle. Wipe the sides of the candle with a paper towel to get rid of any cooking spray and let sit on a towel so that the rest of the ice can melt and the water can drain out.
