I would use water AND ice.
The ice helps filter and cool the smoke, but the water does the same thing (just lesser), so its healthier (and tastier) to do both.

budl0v3r Reviewed by budl0v3r 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
