i heard a drill can work but u need a diff type of drill...whats the best way?

You probably don't need a different drill..just a different drill bit. They have special ones for metal, wood etc so I suppose their must be for glass too. Check google

I believe you need a diamond drill bit. I searched this up a while ago cause I too wanted to make a bong out of something made of glass. I ended up just going with a 2 litre bottle because I didn't want to go out and buy a diamond drill bit at the time. good luck with that

Pretty expensive for a drill bit

yeah thats ridiculous. you're better off buying an already made glass bong, or be cheap and make one out of a bottle. to be honest a 2 litre isnt that bad at all, if made correctly it can last months.

hey man i made a glass bong out of an absynthe bottle, you can use regular high speed steel bits but it just takes ages, just have the bit doing 1-2000rpm and use a bit of oil as lube and get into it. i used some stainless tube on mine, works mint,
