those glasses made out of bottles

The other day i tried to make a drinking glass out of a glass coke bottle. Kind of like this. Its super easy, all you need is a bottle, a blow torch, something to score the glass with, a sink full of water, and some sandpaper. I have seen them sold for up to $45 for a set of six. So, this seems like another opportunity for some micro finance. It would be interesting if somebody could develop a business that is based around a coop type model for making and selling various upcylced glass products and use it as an economic development tool at the same time.
