ABSTRACT:
An improved water pipe or bong wherein the water that is used to filter and cool the smoke is caused to flush up the inhalation tube, thus pushing the smoke into the smoker's lungs. To enhance the flushing effect a water trap is employed to stop the water suddenly and the combustion bowl can be sealed off from the rest of the pipe.
