How to..?

[blades/of/joy]

i've had a question about making a hooter for the blades.
whats the easiest way to break the bottom out of a glass bottle without the bottle spidering?

A glass or bottle cutter which came as common sense to me but idk...

you could try this method: LINK. it takes a while to get it right but i've seen it done perfectly where the bottom of the bottle falls off in a clean circle
