Nontoxic metal alloy that is liquid at room temperature


liquid metalMercury is bad for you. If you want to play with a nontoxic metal that melts at low temperatures, you can buy little bottles of it at Scitoys.com. Simon Field, the proprietor, sells two kinds.

In the photo above, I am holding two small vials of liquid metal. The vial on the right contains gallium, an element that melts at 29.76° Celsius (85.57° Fahrenheit). The vial on the left is an alloy that contains gallium, indium, and tin, and melts at -20° Celsius (-4° Fahrenheit).
