Step-by-step instructions to building more than 30
fascinating devices are included in this book for
workbench warriors and grown-up geeks.
Detailed illustrations and diagrams explain how to
construct a simple radio with a soldering iron,
a few basic circuits, and three shiny pennies.
Instructions are included for a rotary steam engine
that requires a candle, a soda can, a length of copper
tubing, and just 15 minutes. To use optics to roast a
hot dog, no electricity or stove is required, just a
flexible plastic mirror, a wooden box, a little algebra,
and a sunny day.
Also included are experiments most science teachers
probably never demonstrated, such as magnets that
levitate in midair, metals that melt in hot water,
a Van de Graaff generator made from a pair of empty
soda cans, and lasers that transmit radio signals.
Every experiment is followed by an explanation of
the applicable physics or chemistry.
