This website gives specific instructions on how to build a flying helicopter toy. I was a little confused at first because the begging started like this "Soak the tongue depressor in the boiling water for at least 30 seconds. This will make the wood slightly more flexible so you can shape it into a rotor. Remove the tongue depressor from the water with a pair of tongs, and try to twist the stick in the middle. You will want to try to twist one side forward while twisting the other side backward. Hold in position while the tongue depressor cools. You may need to repeat this step a few times. Ideally, you will shape the depressor so one half is angled. If you have trouble bending the wood, try using a file to at least angle the edges." Using a tongue depressor and and boiling water to make a helicopter did not seem practical.  The article also tells you how to decorate it without ruining the desigm.

The second post gives a different way to make a helicopter, using aluminum foil, straw rubberband and christmas ornaments.You need a straw one rubberband a christmas ornimat hook and and alluminum sheetind or just card paper also a small sphere shaped beed with a hole in the middle.So you cut the straw the lenth you want your heli,then take the ornimat hook and bend it to make a small hook at the one end,then take your paper or metal sheeting an cut two thin rectangles about the lenth of the straw.bend to make an airfoil  on each end then poke a hole in the middle.put your hook in the hole then glue hook a rubberbsnd on the hook you made then fish it into the straw tape the rubber band once you pulled it through then make one mor propeller glue to the bottom wind up and let fly.

This website helps when working on the propeller, we cant use this design alone because it does not use batteries or motors, but we can use it in order to build a succesful propeller. To make a propeller the maker suggest we use a block of soft pine, 8 inches long, 2 inches wide, and 1/2 inch thick. The dimensions are not critical. A 10 inch dowel, 1/4 inch in diameter. A drill or auger with a 1/4 inch bit. A wood file or shaping tool, or a whittling knife. Power tools like a drum sander or belt sander make the job go much faster. A drop of white glue. also that the air does not speed up as it moves over the curved top of the wing, but it does slow down as it encounters the tilted bottom of the wing. We can measure the pressures on the top of the wing and on the bottom, and the difference is lift. We get the same value for lift whether we look at the mass of air moving downwards, or the pressure difference between the top of the wing and the bottom, because they are two different ways of looking at the same thing.
