Toys Moved By The Wind
Who am I to blow against the wind? *
Don't confuse them with wind-up toys. Yes, most of these toys are also purely mechanical. But they don't have real engines or any complex mechanism. These toys are powered only by the wind. Wind power typically causes some kind of spinning which makes the toy move. Except with kites. They are entirely different matter.
Let's have a look at some cool wind powered toys and see how they work:
Wind turbine science kits
One of the best features some of these kits have is to use the wind power for lifting heavy weights. This is achieved only through transformation of mechanical power, without any electric conversion.
I love these kits. But I know you might be here looking for toys that are more old fashioned. So here's one:
I bet you've made at least a few of these as a kid. And I bet your hands itch to make one even now. That's what I call a really simple mechanical toy. Back when I was a kid you couldn't find these at the store. You had to make them yourself anyway. And here is how you can do this now. (Of course now you can just buy everything.)
Bloody simple, this toy is still educational. It teaches how the straight movement of the wind can be turned into rotating movement of the wheel. Don't people use the same principle in most of their engines? Rotating movement does everything, so once the children understand it, they are ready for understanding the Theory of relativity (OK, almost).
Pinwheels are just simplified versions of what follows:
Of course not all of these toys should look realistic. Here's one that's fun and easy to make yourself.
Weather vane toys
Even the real weather vanes don't differ much than the weather vane toys. All they do is to show the wind direction. It's a bit of exaggeration to say that they are powered by wind although indeed it moves them. They are nice accessories for your home.
And finally, kites
Maybe the simplest and still the most popular wind powered toys. Kites don't have gears inside but don't underestimate their complexity. The shape, position and aerodynamic of the kites defines how well they'll fly. There's a lot to learn from these centuries old toys.
You can buy all kind of kites with or without frame, with all kinds of drawings on them and all kind of interesting shapes - for example a kite looking like a spaceship. Of course it's more fun to make your kite yourself. Here's a site that contains many good guides on this matter.
