over here they get called buckets
havent had one in a while, but it does get you high as fuck
cains your lungs, i cnt do a decent size one without coughing
my mate who used to live in lazenby had a 8 litre one
4 two litre bottles together, he took it out of an empty bin filled with water
never had one myself,but im sure it would fuck you up :stoned:
