Did you ever watch someone mash up an onion, add a drop of this and that, and
share the astonishment of seeing the stringy strands of real DNA appear? Adam
Hart-Davis and Paul Bader have taken kitchen science a step further in Local
Heroes Do-it-yourself Science. First, they鈥檝e gone upmarket鈥攁 kiwi fruit
replaces that eye-watering onion鈥攁nd secondly, they鈥檝e put together the
most brilliant bunch of unlikely experiments. A home-made fax machine stars, but
make time for the Archimedes screw constructed from lolly sticks and a soda
bottle. Published by BBC Books, 拢9.99, ISBN 0563551658.
