Lately, I've been scraping the bottom of the barrel for material. I've resorted to recycling stories to tell my three-year-old and challenging my nine-year-old to solve the "three houses, three utilities" problem. (She's going to be mad when she finds out it can't be done.)
I found Be the Coolest Dad on the Block just in time. Subtitled "All of the Tricks, Games, Puzzles and Jokes You Need to Impress Your Kids (and keep them entertained for years to come!)," this book is filled with stuff that has delighted my kids. The authors manage to cram an awful lot of great ideas into 186-pages. There are things to make, like bows and arrow, fire-starting kits, garbage bag kites, and instructions for making animated movies with Lego bricks. There are games to play on in cars and on plane rides and answers to questions like "Why is the sky blue?" and "Why is the sea salty?" I like the list of "misconceptions" the authors encourage you to share with your kids ("There's a parallel universe on the other side of mirrors where people exactly like us do exactly the same things.")
The first thing we did was make a duck call out of a drinking straw. We then modified it by poking holes in the straw so we could vary the pitch. My nine-year-old loves the "quick-fire puzzles" (Example: A man buys several loaves of bread at $1 a loaf and sells them at 25 cents a loaf. He does it again and again. Entirely as a result of this, he becomes a millionaire. How? ). I make her guess for a few minutes before giving her the answer (I'm not going to give you the answer, either).
I hope they come out with a follow-up book soon. Link
