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. Lets 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
