Reaction of Liquid Gallium with Aluminium

So, today we are going to carry out further experiments with an unusual metal - gallium. This metal has one interesting feature. It is able to create an amalgam with another metal, such as aluminum or iron. To demonstrate this property I will conduct an experiment. Let’s take the aluminum radiator from a computer and drip about 2 grams of liquid gallium onto it. To speed up the reaction of gallium with the aluminum, its surface was scratched with a knife. During amalgamation, gallium penetrates the crystal
