This was a fun and surprisingly easy project (we made 200 in a few days) with the added element of danger-transforming every glass object you own into mercurial glass.
The first step is the most difficult-finding the Krylon Looking Glass spray paint. Oh sure. It's in craft and hobby stores, however if you are like me you will be looking for the large spray paint can. Had I known it was a delicate smaller can I would have been finished a day earlier. Thus I have given you a can shot for scale.
