Query: How to Cause Mayhem and Get in Trouble

Some of these "science experiments" are simple and relatively harmless. Others provide unsupervised children with recipes for disaster. The book should come with a child-proof cover or a trigger-lock. Not that it contains plans for thermonuclear devices, but several of the projects can damage property or cause injury if not properly carried out.While each project has a set of fascinating "scientific" tidbits & trivia to go with it, the book is almost entirely lacking in helping children understand or use the scientific method or understand much of the basis for what they are doing. This is a "Mad Scientists' Club" handbook, just a several steps short of the Anarchists' Cookbook, but headed in that general direction.On the other hand, parents may find themselves reliving their own nerdy & awkward years helping their children be "mad scientists." It could be great fun. But keep the book locked up. A little knowledge can be a dangerous thing!
