How to make a hole in a glass bottle

hi all, is there an easy way to make a hole on the side of a glass bottle using a common drill or any other common tool?

You can buy a special drill-bit for tiles and glass. It looks like a small and very pointy spade (not a spiral).

Put a small patch of masking tape on the spot you want to drill to stop the bit slipping and scratching the glass.

thanks a lot =) ill try to get one of those drills, but do i have to use different drilling speed for glass? the slower the better?

Sorry, I don't know. It's just occurred to me, though, that you could use a dremel or similar to grind a hole.
I've tried a Dremel but it didn't work. Tried several different bits & stones but none made more than a very small dimple. I even broke one of my expensive metal bits, wasn't happy about that. Using the dremel to make a starting dimple seems to be the best use for it. The dimple gives the spade bit a place to start so it doesn't 'walk' all over the surface. It seems that slow but steady (like a regular drill) works better for drilling holes in glass & ceramic, rather than the high speed (and heat?) from a Dremel. That's what has worked for me, anyway. Also, water is an essential to keep things cool. I build a dike around the area using kid's craft clay and keep about a half inch of water in it while I'm drilling. The drilling will take what seems like forever and ever and ever......but sooner or later it will pop thru a tiny bit and the water will drain out. Not much longer after that you'll have your hole.

. I've had pretty good luck using a sharp-pointed piece of metal (eg, knife, icepick) and just pecking at it until I have the right size hole. Very slow process, but it works. A drill bit designed for glass will be much quicker and will probably make a cleaner hole, but I always seem to crack/shatter the glass with one - YMMV.
