this is cool... a paper gyro!

Postby Learjet » Wed Aug 26, 2009 9:32 am

Are you often asked, "how does a gyro plane fly?" Here's a great way to demonstrate it with a quick and easy to make paper gyro! vhpy

Image
Cut out a 6 1/2-inch-long by 1 1/2-inch-wide strip of paper. (Note: We found that using pinking shears made the gyrocopter fly better, but one cut out with ordinary scissors works well too.) Starting at the top, cut a 3-inch slit down through the middle of the strip to create a pair of wings.
Image
Fold down the wings in opposite directions from one another. Attach a paper clip to the bottom of the strip for weight. Now your child can drop the finished gyrocopter from an elevated spot, and it should spin to the ground.

Hi Dave.

Below is one of the more entertaining projects I have involved my kids in. You should try it:

You can build your very own fly powered model aeroplane if you have:
Match stick
Blade
Freezer
Glue
Glass pot
Patience (To catch flies)
Attachments

Take a wooden matchstick and slice a thin sliver from one side. Then cut the remaining stick in two, lengthwise. Make sure you leave a little of the red tip intact for effect. Discard one half

Make the aircraft by glueing the sliver of wood - the wing - across the remaining part of the matchstick - the fuselage. If you want, you can use little scraps to make a tail section. Or you can make a biplane. Or you can use a couple of thin slices of balsa to make a huge wing, one that will carry maybe twenty engines. Indulge your aeronautical whims. Think of lift, think of thrust, think of innovation without the benefit of an industrial policy

Catch a bunch of flies. Put them in a jar and put the jar in the freezer. In a few seconds the flies will be chilled out completely. This is called cryogenics, and it has its drawbacks. For example, the flies will be dead flies if you freeze them too long. Dead flies are no good. So if you’re a tinkerer, refrigerate your flies. It takes longer to make them comatose, but they have a higher recovery rate than the ones you leave in the freezer next to the burritos

Meanwhile, put a tiny drop of rubber cement at each place along the wing where you want an engine

Take the flies out of the freezer. Attach the abdomen of one frigid fly to each drop of glue. Make sure all the flies are facing the same direction

Breathe life into the flies. A miracle: A gentle puff of your warm breath will resuscitate the flies

Launch the aircraft. It should fly like a charm, and, far from being cruel to the flies, you’ll be teaching them a new and valuable thing, one that brings us to the virtue of this exercise. For we see that while flies think a lot alike, have a great deal in common, share many of the same hopes and dreams, they never act in concert, as a team, with regard for the worth of other, neighboring flies until forced to by grim circumstance - as, for example, when they are harnessed to fly and either first experience the exhilaration of high-altitude cooperation or die. Redeemed by such a critical choice, they’ll soar like a glider, race like a Stealth airplane

Hmmmm. Nice new picture there Len. Is it any more than a coincidence that the Orion happened to be captured in the same snap as your trusy Sycamore? If not, I hope our hangar landlady doesn't see it, since I fear our rentals will escalate sharply! :lol: Tell more :?:
