Gallium Is A Metal That Melts In Your Hands
When you think of metal, you most likely think of strength and toughness. The element gallium is an unexpected metal in that regard. It's a soft, silvery-white metal that is solid at room temperature, similar to aluminum, but it can literally melt in the palm of your hand. The melting point for gallium is relatively low, at 85.6°F (29.8°C). However, the boiling point for this element is quite high, at 4044°F (2229°C). This quality makes gallium ideal for recording temperatures that would destroy a thermometer.
