water balloon luminaries

I found this link via @SisterDiane on Twitter and I now know what I'm going to do with my left-over candle wax. I have a candle warmer and after I've extracted the wick and all the yummy smell from them, I wasn't sure what to do with them. I was thinking about freecycling them to a candle crafter, but this looks like a lot of fun and relatively simple to do. Now, I just need to add a few old pots to my thrift store list and get some water balloons! Yay! New project!
