The best way to take a cool hit is not based on the pipe, but your mouth. When you're inhaling, don't use your diaphragm. First, start with your mouth cavity very small, tounge blocking your air passage, with your lips around the pipe. Light the flame, and drop your jaw, but keep your lips around the pipe. You've just made the space in your mouth cavity much bigger. The air is pulled through the pipe into your MOUTH (read: not your lungs). Once it's here, breathe in through your mouth. You'll pull that mouthful of smoke down with the air.
