A collection of physics demonstrations costing very little, but illustrating concepts in amazingly simple and playful ways. Food coloring and glycerin are swirled and then mysteriously unmix. How to catch a row of pennies placed on your arm. Jearl Walker writes: "... dipping into this collection is much like opening a holiday gift and discovering a marvelous little toy that then holds your attention by some curious performance ... This book precisely reflects the way science education should be, especially at the introductory level."
