do you crack nuts with a piece of string? Reverse gravity? Cobble together
a clock out of a coffee cup, a soda bottle, and some water? Use a vacuum
cleaner and nineteenth-century railroad technology to fashion a makeshift
bazooka that can launch paper projectiles? Create a rainbow in a block of
Jello? This is a one-volume romp through a whole array of counterintuitive
science experiments that require little more than common household items
and a sense of curiosity. Prepare to have your surprise sensors on
overload as Neil Downie stretches math, physics, and chemistry to do what
they have never done before.
This book describes twenty-nine unusual but practical experiments, detailing how they are done and the math and physics behind them. It will delight both casual and inveterate tinkerers. Of varying levels of complexity, the experiments are grouped in sections covering a wide field of physics and the borders of chemistry, ranging from dynamic mechanics (''Kinetic Curiosities'') to electricity (''Antediluvian Electronics'') and combustion (''Infernal Inventions''). The chapters are titillatingly titled, from ''Twisted Sinews'' and ''Mole Radio'' to ''A Symphony of Siphons'' and ''Tornado Transistor.'' More-detailed explanations, along with simple mathematical models using high-school level math, are given in boxes accompanying each experiment.
Armchair scientists will welcome this edifying and entertaining alternative to idleness, not least for the buoyant prose, enriched by historical and literary anecdotes introducing each topic. With this book in hand, tinkerers, whether dabblers in science or devotees, students or teachers, need never again wonder how to impress friends, the judges at the science fair, and, not least, themselves.
