Gallium, you see, melts at 30 o C, which means that on a hot day, you hold it in your pocket at your peril. Surprisingly however it''s not very volatile. In fact Gallium has the largest liquid range of any material known to man. Its boiling point is just over 2400 o C. So unlike other liquid metals, there is no toxic vapour to worry about.
