hey good idea i made one to lol
heres wat i did
1. i started to sctrach one of the sides w/o a label
2. scratched deep enough that a regualr wood drill bit could bite a lil bit into the glass
3. one the drill bill is down far enough and it seems like its not going down ne further start to chip inside the little circle the drill bit made
4 you should come out with some on even edges that will be fine
5 i hot glued a piece of steel then i found this other steel plumbing thing arund my house nd used that as a bowl.
my hits were almost yellow just dont get caught..... i had to break mine
