Ready to become a scientist and conduct your own experiments? Gallium Metal is an amazing non-toxic element with fascinating properties for kids, teenagers, adults, or teachers to explore. Gallium is a silvery metallic conducting metal that is slightly brittle but at temperatures above 86°F it will melt into a liquid pool of metal. Gallium is 6 times denser than water so holding and touching the liquid metal it is something you really have to experience for yourself.
