What could be more entertaining than grossing out parents with a homemade batch of disgusting runny slime? Or making miniature cave stalactites and stalagmites out of saturated salt solutions and string? These 50 irresistible experiments, explained in terms that children will both understand and appreciate, show just how enjoyable science can be--and that's definitely cool. Even the look of the book has real appeal. All the activities appear on colorful illustrated spreads with an engaging cast of kid characters who show how the science fun is done. Most of the experiments use ordinary household materials, and they provide some delightful visual and tactile effects. See what happens when cola and mint come together. (Hint: take cover!) Watch a rubber balloon inflate itself over a bottle. Bounce a raw egg--with no breakage. Every idea is a winner.
