I use icing sugar, and blow it through Bunsen tubing attached to the end of a funnel which is under 2 Bunsens clamped sideways on 2 stands pointing inwards over the funnel. Much more fun. And you can find different powders to do it with all based around the same sugary concept. There are ways of getting a tin with icing sugar in to blow the lid off too. Sprinkling it onto candles just isn't as good when you know some of the better alternatives :P

Plus, the instrument Dave has built with which to do this is known as the "custard crack pipe", due to it resembling, um, a crack pipe...

It also works with sawdust, flour and, the one I used to experiment with, coffee whitener. The Mythbusters did one on a massive scale with coffee whitener.
