This is another Klutz book from the scientific staff at San Francisco's Exploratorium. All Klutz books look at learning as play, so this time we are playing with magnets. Although children will look on these books as just a bunch of fun things to do, they are learning at the same time.
This book currently sells for £9.99 new at Amazon and I would strongly reccomend buying new unless you are certain any used copy comes with the full set of magnets. Once again, a large portion of this book will not work with whatever magnets you happen to have lying about the house.
Some of the tricks include a perpetual motion machine ( we havent got this one right yet), levitating paperclips, jumping magnets, a bananna compass, and magnetic boat. The idea of the magnetic boats is that the opposing forces of the pill magnets will keep them away from each other, but it so much more fun to get big magnets and have races and storms and crash eachother about.
Along with all the tricks there are pages of fun facts mixed in, like the fact that magnetite, a natural magnet is magnetized by iron eating bacteria. The scientific explanation of why each trick works is also included, in language that even young children can understand, so all the while they are having fun, they will be learning thngs lie how a compass works.
I've given this book five stars because it is a really good book in its own right, but compared to the Explorabook I reviewed earlier, also by Klutz, it's not quite as good. I would also note this book is smaller than most Klutz books only 7"x5".
