Yes. That's the difference between a bong and a piece. The water in the bong cools and filters the smoke making it feel much smoother.

EDIT: Try putting cold water and ice instead of just plain water. :thumbsup:
werd328 Reviewed by werd328 on . 2 Homemade Bong Questions Hello. I am interested in making my first homemade bong, and I have a few questions. 1. Does the bong need to have a carb, or do I get the choice between the carb and a slider? (I understand how to use each, but i don't really understand what it actually does.) 2. If the bowl piece were connected to an empty pen (this is where the smoke will be drawn into the bottle), should this opening in the pen be under the water? Any other tips would be great. Thanks.
