Summary

Description The gallium beating heart is a chemistry demonstration in which a drop of gallium is made to pulsate, like a beating heart. The gallium beating heart is similar to the mercury beating heart, but gallium is much less toxic, so this demonstration may be preferable. To make this experiment I have melted piece of gallium in 20% hot sulfuric acid. Next, i am adding to the solution droplets of 5% potassium dichromate solution. A sound effect of a beating heart has been added to this video.
