How Do You Make A Wind Turbine Out Of Straws?
Making a small wind turbine out of straws can model larger-scale versions that generate electricity. This turbine project includes miniature airfoil blades and pivots on a central axis. It also can illustrate how “wind energy” is turned into “rotational energy” using “turbines.” Step 1 Select the straws to use for your turbine. Large straws catch more wind but tend to bend more. Bendy straws are inappropriate for this project because of the “bendy” portion. Step 2 Cut two, 4-inch pieces of straw tubing. Cut down the sides of the tubes to separate the tubes into four half-tubes. Stack the half tubes to make sure they all are the same size. If not, cut them so they all are the same length and width. Step 3 Cut the stack so that the straws slope inward on one side and are all uniform. The cut should start at one end (about 1/3 of the way in from the side) and continue down to the far corner of the straws. Keep the large part of each half-tube in the stack that you cut, which is now a “bla
