WebNov 25, 2024 · Gallium transitions from a solid to a liquid slightly above room temperature. The low melting point and resemblance to stainless steel makes gallium perfect for the disappearing spoon trick . Gallium is also used for the gallium beating heart demonstration, which is a much safer version of the classic chem demo that uses mercury. WebThe mercury beating heart experiment is a popular chemistry demonstration based on an electrochemical redox reaction that causes a blob of mercury to oscillate, resembling a beating heart. The gallium beating heart is a chemistry demonstration in which a drop of gallium is made to pulsate, like a beating heart.
