Voiceover
An antique carbide lamp contains two chambers. The bottom chamber is filled with calcium carbide. The top chamber is filled with water. A dial regulates the amount of water that drips from the top chamber to the bottom. The two chambers are screwed together. Water drips onto the calcium carbide, forming acetylene gas. The gas is lit with a match.
