hollow out the pen. Put tin foil around the and inside the pen (it's hard to explain but you gotta like put it on one side).Start to burn a hole near the bottom of the watter bottle, before it completely melts push the pen through it. Leave the pen there. Burn a hole near the top of the bottle now(for the carb). Put some water in it. Place a bowl that will fit in the pen bowl. Cover the carb, light, inhale, release carb after you fell you can't hit it anylonger.
