Uranium is extremely hot Extreme radiation its got Causes death by the pounds Its found in a lot of rock mounds Its used for nuclear fuels But its temperature doesn’t get cool In 1789 I was discovered by Martin Klaproth He of course found it in an igneous rock Its used for inertial guidance devices Its radiation is going to cause a crisis Its classification is rare earth The beginning of time is the time of its birth
