Fantastic bucket bong diagram.

I also remember using glass milk bottles. Drop a coin in and smash out the bottom.

Then heat two knives up 'till they’re glowing red and put a bit of hash on them and suck the smoke through the bottle.

It’s a precaution. If you were to damage the exposed battery it could cause it to heat up and probably catch fire.

I had no issues when I did mine.
