Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Bomb disposal Bomb disposal Bomb disposal is the process by which hazardous explosive devices are rendered safe. "Bomb disposal" is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the public safety roles of public safety bomb disposal (PSBD) and the bomb squad. "Bomb disposal" does not encompass the remediation of soils polluted with explosive materials. The first professional civilian bomb squad was established by Sir Vivian Dering Majendie. As a Major in the Royal Artillery, Majendie investigated an explosion on 2 October 1874 in
