The Twenty Demonstrations Guaranteed to Knock Your Socks Off! book showcases the exciting, creative and unique demonstrations of chemistry teacher Bob Becker. Complete write-ups are included as well as detailed information about each demonstration.
Methane Mamba, Underwater Fireworks, Kaleidoscoptical Activity and Flaming Vapor Ramp! These are a few of the exciting, creative and unique demonstrations by Bob Becker that have achieved star status in the collection of notable chemical demonstrations. The hallmark of Bob’s demonstrations is an uncanny ability to recognize small details amid the myriad exciting chemical and physical observations that arise. When taken together, the observations shine a powerful lens onto fundamental principles and concepts.
In the CO2 Crystal Ball, for example, Bob describes how the eerie dome of soap film on top of a bucket of dry ice in water stops growing, even as the dry ice continues to vigorously sublime. Bob uses this observation to tie together concepts of sublimation, solubility and equilibrium—a remarkable tour-de-force for a demonstration that has become a staple of Halloween demonstrations all over the country.
Complete write-ups for each demonstration are included in the book, Twenty Demonstrations Guaranteed to Knock Your Socks Off!, Volumes I. The book contains full details on how to perform each activity as well as a history of the chemical concepts being taught, preparation, procedures, reactions, safety precautions, tips and references.
