Does anyone know how to etch a hole in a glass bottle?

I want to etch a small hole in a glass bottle for an agricultural project Im working on, but I have no idea how to do it without breaking the glass. It needs to be tiny to let water out very slowly, so precision is important. I cant spend tons of money on this, so any suggestions on household tools would be great.
I dont know if there are any glass cutting shops around… really Im looking for something I could find at home or a cheap thing I could buy..
