Demonstration showing that when a finger touches molten lead that is hot enough, moisture from the finger vaporizes instantly and creates an insulating layer of steam that protects the finger for a fraction of a second. However, if the metal is just barely molten, not enough steam is created and some lead may solidify onto the finger where it would rapidly transfer enough heat to cause a serious burn. Here nontoxic plumbing solder was used in place of lead, which has a melting point of around 400°F. When the temperature reached 500° the experiment was done. Series
