Mason jars are pretty tough... I used a glass/tile drill from Harbor Freight... just add water to keep it cool and the dust down... (don't breathe glass dust!)

Other than the fact that I would be afraid of breaking it, that is cool as heck.  A jar full of major mojo.   Neat idea.  How did you drill the hole?  Diamond tip bit?
