Well, I'll keep this one short and simple. I disassembled a lithium battery pack from an old cordless phone and then extracted the lithium metal foil inside (Experiment 2: Lithium Battery). The foil was stored in a jar full of baby oil. My baby oil was made out of mineral oil to preserve the lithium. When I was ready to light the metal, I dried it off with paper towels and then folded it neatly. The lithium was readily ignited with a propane torch.
