keep a steady flow of water on hand, not like drenching it, but keep it well wet and cover it in masking tape before hand about 2 or 3 layers, with some time and patients you'll have a perfectly cut hole, and there are special drill bits to buy that make it easier and more succesful....a set of them in about 5 sizes at walmart is about 12 bucks.

Also, what other options could there be rather than buying a glass bowl for it. Rating: 5
