Water Puff – Instant Portable Water Pipe – With the Water Puff, you can turn most plastic or glass bottles into a fully functioning water pipe. This tool is extremely useful when on the go. When you’re done, you just throw the bottle away.
Two things to keep in mind with the Water Puff. First, you should take the plastic ring off the bottle before installing the Water Puff. This ensures an airtight fit. Second, you may want to poke a carb hole in the bottle if it’s plastic. Heating a paper clip usually works well for this.
