Magnetized Water: Science or Fraud?L. Lahuerta Zamora, G. M. Antón-Fos, P. A. Alemán López, and R. V. Martin Algarra Commercial water magnetizers provide a unique opportunity to help university and secondary students develop appropriate skepticism against extraordinary claims and use testing as the basis for their scientific evaluation.

Fog Machines, Vapors, and Phase DiagramsEd Vitz This series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles. Vitz, Ed. J. Chem. Educ.2008, 85, 1385.

Drinking Bird (GCMP)David M. Whisnant Drinking Bird: this is a resource in the collection "General Chemistry Multimedia Problems". The drinking bird's felt-covered head dips into the beaker of water as it bobs up and down. The tube goes from the bottom of the body to its head. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

Electrolisis 1 (GCMP)David M. Whisnant Electrolisis of Water #1: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will contrast the electrolysis of water with boiling. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
