Principle: Aluminum is a highly reactive metal, but the alumina layer on its surface prevents it from reacting completely with the oxygen in the air. Mercury destroys this protective layer, causing the aluminum to rust rapidly. This is a time-lapse video. The actual duration of this process is about half an hour. If you scroll the image down, you will see a large amount of aluminum rust powder at the bottom. Fun fact: This is one of the reasons why mercury is strictly prohibited from being carried on airplanes. There are legends that during World War II, some American commandos carried mercury to destroy German aircraft. Recorder: Theodore Gray. Risk: Medium-Low. Mercury in its pure form is toxic and not edible; please conduct experiments in a well-ventilated area to avoid poisoning from mercury vapor.
