In this tutorial, we learn how to make a water bottle bong. You will need: a water bottle, a pin or needle, a container for the weed, a lighter, tape, and a metal pen casing. First, take the cap and paper off the water bottle and then heat your pin up with the lighter. Push the pin into the top side of the water bottle, just two small holes will be fine. Next, push the pin into the side of the water bottle, making a hole big enough to put the pen casing through. When finished, push the pen casing into the hole and you can now use this as a bong after you fill it with water.
