A way to drill holes in glass

[Orchidtinkerer]

have you tried the sellotape trick at all waterwitchin to see if that makes it any easier?

You can do all you do but just place a peice of tape over the spot you are drilling before you start. It should make drilling easier and prevent cracking.

It is something plumbers do to avoid cracking tiles in bathrooms so if it works on bathroom tiles it shoud in theory work on glass bottles too.
