I know plenty of people using diffrent things.

Pref water, but if were in the middle of nowhere it's the cleanest liquid we can get for bong water.. So Evian Sprite Vodka Beer.. Shit like that...

Vodka has to have water with it too tho.. Feels fucking nasty on your chest.. Saying that im not a bong kinda person anyway just hookah's and big fat spliffs for me

Peace :thumbsup:
