For nearly a decade Theodore Gray has been demonstrating the basic principles of Chemistry and physics through daredevil experiments that he executes, photographs and writes about for his monthly Popular Science column, Gray Matter. In the first collection of experiments, Theo Gray's Mad Science: Experiments You Can Do At Home, But Probably Shouldn't collected 54 experiements previously published in Popular Science, along with hundred of photographs, many of which were not published with the original columns. The experiments were organized into sections, from experiments that cause fiery explosions to those that use food or household products and more. Now comes the second volume of mad scientist experiments. Theo Gray's Mad Science 2raises the stakes with another 50, even more dramatic, daring and enlightening demonstrations in which Gray dips his hand into both molten lead and liquid nitrogen to demonstrate the Leindenfrost effect; crushes a tomato between two small magnets to demonstrate the power of neodymium-iron-boron magnets; shows the terrifying and deadly inferno that erupts when a frozen turkey is lowered into a deep fryer; and sculpts lovely trinkets out of solid mercury to demonstrate how the state of matter depends very much on the temperature at which it exists.
