ice would work.

i use really cold water and barely feel my hits
klondike_bar Reviewed by klondike_bar on . Do you think ice in a bong really cools the smoke? I just bought myself my first piece here in NZ. It has a large twist/ ice catch. I was wondering is it more just for show or do do you think the ice really manages to cool the smoke in those few seconds your hot smoke rushes by it? Rating: 5
