This book, by the folks at the Tinkering Studio at the awesome Exploratorium science museum, is filled with creative applications of everyday materials. To only list a few of my favorites:
- Inflatable plastic bear, placed over NYC subway vents and expand when a train goes by, to the delight of passerby (page 190)
- Using foam and paper to build cam mechanisms - mechanical linkages that transfer rotary motion to linear motion, or vice versa (page 146). This was mind-blowing - what a novel human invention, on the same level as the wheel, but I hadn't encountered it before!
- Yarn-bombing and funky science creations out of textiles (page 98). Such a mash-up of disparate concepts! So creative! So colorful!
- Battery + magnet + bended copper wire = homopolar motor (page 112). You can bend the copper wire into any shape you like, so long as it touches one end of the battery and the magnet on the other end, and it spins... (the battery also heats up, but you get some amount of whimsical glory until then).
My first read-through, I was disappointed in a few of the subjects for being pretty photos of things that didn't actually work - in particular some of the "Instrument a Day" ideas were things that could be done in less than 5 minutes. Some have issues with the "Maker" community for focusing too much on "create something, anything!" and not enough on studiously attaining the technical know-how through hard work. I am ok with giving credit to a creation even if it doesn't require too much technical background, so long as it exhibits a novel creative take on things that I wasn't expecting. Then it is art, and my brain has to think differently, and I really like that. Most of this book satisfied that criteria, but not all. Some of the art projects could have been 10x better if they had only done some more technical research, instead of just hacking based on limited info. So, originally, I gave this book four stars.
On my second read-through, however, was when I encountered the homopolar motor instructions. While they don't explain how the physics behind why this works in the book, opting instead to just have photos and instructions, the sheer whimsy and simplicity of the thing was amazing. It made the entire book worth 10x more in my mind.
Overall, sadly, this is not a book through which you will learn engineering concepts. It isn't the science book that I was expecting. That makes sense, though. That's not their goal. They want to inspire people to tinker, not become engineers.
