This video is a tutorial on how to make a smoking pipe out of a highlighter marker. To begin, you will need a highlighter marker, pliers, and a socket wrench. Use the pliers to remove the sponge tip from the highlighter marker and the back cap piece. You may discard the sponge tip but do not discard the back cap piece. Empty the highlighter marker of any tubes that are inside. Insert the socket wrench so it is less than an inch in the highlighter. If you insert it too deep, you risk burning the plastic while you're smoking. The video suggests this is a discreet way to carry a pipe with you for smoking.
