How to DRILL a HOLE in the GLASS, Bottle or Jar - FAST and EASY

It is easy to drill a hole in the glass bottle or a jar using special drill bits. Have a household or craft project that requires you to put a hole through glass? Drilling a hole in glass can be done with a regular electric drill if the correct drill bit is used. The key to drilling glass is to use material harder than the glass itself. You can drill holes in wine bottles, aquariums, mirrors, glass tiles - basically all kinds of glass. However, the one major rule is that you should never drill a hole in tempered or safety glass. Tempered glass will shatter upon contact with the drill. To determine whether glass is tempered, look at the four corners of the glass. If the glass is tempered, the manufacturer is supposed to etch the glass at each of the corners.
