Kids love science experiments, especially ones that involve blowing stuff up. We've filled this book with the answers to the "hows" and "whys" of explosions. To make it even better, everything in this book is absolutely safe - from the Geyser Tube (that turns table salt and a bottle of soda into a backyard geyser) to the Klutz-custom depth charge. It's all safe... and unbelievably fun.
