Potassium Metal Is Explosive—Do Not Use It!Andreas Grubelnik, Veronika R. Meyer, Peter Bützer, and Urban W. Schönenberger The reaction of sodium with water is a spectacular and essential classroom demonstration. Many teachers want to show also the more violent reaction of potassium. We propose not to do so because explosions can happen even before the metal is in contact with water. Grubelnik, Andreas; Meyer, Veronika R.; Bützer, Peter; Schönenberger, Urban W. J. Chem. Educ.2008, 85, 634.
