Needless to say, there's nothing "dangerous" about these - just full of exciting and wonderful discoveries to come. There's more than a little bit of Huckleberry Finn here. Entitled "Things To Do" and "Things to Know" the book covers say it all. Full of "secret" information and mysteries, they are an endless wonder for growing boys - and girls.
How about Spies-Codes & Ciphers Making a Battery, Building a Workbench, Sampling Shakespeare, Skipping Stones, Fishing, Dog Tricks, Juggling - it's all here, plus lots and lots more. These are the ultimate anti-TV, anti-couch potato book, answering the question "What's there to do?" Made in the USA.
