Supersaturated Solution Crystalization Posted by: yrunido
Video duration: 66 seconds Dr. Adam van Wynsberghe, UW Madison, pours a supersaturated Sodium Acetate solution onto a single crystal of the solid. This crystal, known as the seed, creates a template for the precipitation of the supersaturated solution. Related: chemistry, cool, demonstration, madison |

Barium Hydroxide Octahydrate with Ammonium Thiocyanate Posted by: yrunido
Video duration: 81 seconds Associate Lecturer Adam van Wynsberghe, UW Madison, demonstrates an endothermic reaction. Before carring out the reaction, he applied a thin layer of water to the top of the board, and placed the beaker on top. Related: chemistry, cool, demonstration, endothermic, madison |

Supersaturated Solution class participation Posted by: yrunido
Video duration: 72 seconds Dr. Adam van Wynsberghe allows one of his Chemistry 104 students to duplicate the experiment demonstrated earlier, in which a supersaturated solution of Sodium Acetate was poured on a seed crystal, causing instant precipitation. Related: chemistry, cool, demonstration, madison |

Thermite Reaction Posted by: yrunido
Video duration: 19 seconds Associate Lecturer Adam van Wynsberghe, UW Madison, demonstrates an exothermic reaction while teaching about Gibbs free energy. Although he admits it has little to do with Gibbs free energy, it is "really cool." My camera had a bit of trouble with the intense reaction.

Arc Ignition Posted by: yrunido
Video duration: 26 seconds Lecture Demonstrator James Maynard, UW Madison, uses an electrical arc created by a generator to ignite a white powder. The white powder is one of the most efficiently burning substances known, and I haven't included it's formula as it's been linked to terrorism. And I forgot to write it down.
