then you need tape, a drill and prererably a glass drill bit (regular will work, i think on low speed for both) and a bottle to apply a slow stream (not drips but not dousing it in water either) use masking tape and apply a few layers over the are to be drilled (completely around the bottle but the middle of the tape should be about where you wanna drill) once done, secure the bottle so it doesn't roll, pick up the drill in one hand and the bottle in the other, start the stream of water on the spot to be drilled and start drilling, go slowly, the faster you press it and with more pressure the chances increase of breaking.
