Back-in-the-day I enjoyed my herbs inhaled thru my diy bong similar to the Waterpuff. First insert a bowl into a hole cut in the top of a waterbottle. Cut another hole anywhere and insert a plastic straw. Add h2o. Boom! Waterpuff stole my idea. I had to buy four just to make sure they worked. The design is timeless. If you want a bong that is straight to the point without a whole lot of twists and turns then Waterpuff is for you. Plus it travels well.
