How do you put a hole in the bottom of a wine bottle without breaking it?

It's not easy! You need a special drill bit. You can sometimes use the one made for drilling ceramics but a diamond bit works much better. & while you're drilling you need to have someone drip water on the bit & the area being drilled. This prevents heat build-up. At least this is how a friend told me she drilled a sheet of glass which is basically the same thing (but not as thick as a pop bottle.

They sell flat nose diamond bits & also have a "how to" section.

I do drill wine bottles with a drill press. This helps because you can exert even pressure. First fill the bottle with cool water all the way to the top and cork it. I use a vacuum sealing cork. Then use some plumbers putty to create a dam at the drill site and fill that with water.
Anyone know how to drill a hole in the side of a wine bottle without it cracking. I make glass blocks as well, but I don't think drilling will work as glass is thin.
