I'm very sorry about the lack of a thumbnail image. I promise I'll fix that as soon as a get a good photo of the lantern in action.
-A water bottle
-Hot glue gun
Heat the nail and use it to bore a hole through the water bottle. Disassemble the lighter and remove the gas tank. Place the gas line nozzle inside the bottle and secure it with a bead of hot glue. Fill the bottle with water, press the valve, and light the lantern!
