Is it the wax that smokes or is it the paper wrapper? I will have to try to make a small crayon candle with a traditional wick and see how much it smokes......I'm thinking just taking a normal tea-light candle since it will not take too many crayons and the wick usually can be pulled out of them easily.......slide candle out of the cup....pull the wick out of the wax and fill with melted crayons......let it solidify and light her up.......maybe light a regular tea-light at the same time for a side-by-side to see which has a longer burn.......crap - I just created a "project" for myself.........
