sentence: Some metals can boil and burst into flames when placed in thermite, such as zinc.
sentences_before: Thermite is not safe to make at home. It releases ultraviolet light which can damage the eyes. It also makes a very hot flame that can melt iron. It is extremely difficult to extinguish. Streams of molten iron can flow out of a thermite mixture, igniting everything around it.
sentences_after: If it is preheated then ignited, thermite can burn very fast, releasing a huge amount of heat and light. If it is dropped in water it can boil water very fast, making an explosion. Dropping it on ice can make the ice explode.
