How would you go about drilling a hole in a glass bottle without shattering it?
I dont have any diamondtipped drillbits or other specialist equipment.
Uhhh, could be tricky.
But I would try packing it tight with fine dirt or something similar, then drill it as slow as possible with a small bit while keeping it wet to collect the glass dust

Use a pointy rock
Plasticene or Blu tack ring around where you want the hole. Fill with light oil - cooking oil will do. Masonry bit at low speed. Scraping some grit off sanding sheets into the oil will help.
Home Depot. $10. Save the headache.
Just use a normal drill, really, really slowly with little force.

I'm gonna agree with this anon. Just buy the right tool for the job. Wife wanted a hole in a champagne bottle for wires. Those fuckers are thick near the bottom. Still took forever even with the right tool.

make sure u use a hammer drill.

Agreed. In my experience, the round diamond tip bits are a lot less likely to crack a bottle and are generally easier to use as well. They are more expensive than the spade bits, but worth a it if you'll be drilling multiple holes/bottles. Either way, drill under running water for best results

Forgot pic
carefully
I drilled a rum bottle a few weeks ago.
I'm super lazy so I just used an HSS bit, the smallest diameter I had 4mm. put a fair bit of WD40 on the hole and just slowly eased it in. Re applied WD40 when the hole could hold a few drops and continued until it went all the way through. Widened it using a larger drill bit so I could run wires through it. Never really got around to it when I sobered up.
These is a but of chipping on the inside form when I widened the hole but no cracks

Anything diamond coated is good for cutting glass. Unless it has to be perfectly round get a diamond coated separation disk
Use a Carbide tipped drill and use paint thinner for lubricant. Keep it lubed during drilling.
I once submerged a glass bottle in water to equalize the pressure in the hopes it would reduce heat and lower the chances of shattering while I drilled it.. Worked pretty good. I'd suggest using a large bucket or plastic tub though, not a bathtub or sink, for obvious reasons.

Not surprising, they are made to withstand internal pressure of 6 atm (+/- 90psi).

fill it with water, immerse in water.
one quick hit with a nail and hammer, I've tryed and failed but some people claims ot works.
