Decorative Candles

I was looking at a video on how its made decorative candles. I was thinking that I could melt down crayons and practice slicing into it and making cool designs so I will so that sometime. Here's a link to the videohttp://www.youtube.com/watch?v=oQfeCrU-7LA   It looks like it takes a lot of work because you have to have all the cuts even on the candle and the cool thing is that when you slice into it there is multiple colors becasue the person dipped the candle into a lot of other colors you have to watch the video
