How does it work? You simply insert a lit smoke into the special holder in the cap. Screw it on and and find the air hole. Cover it with your finger and "Don't lip it! Grip It and Rip It!"
It shoots out a steady heady long white straw of smoke that you inhale inches away from your mouth making it seemingly one of the safest ways to share a smoke. No more wet passes! No more cooties!
