A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.
1. Cut a circle 3 inches across from a thick foil food tray. Pierce a small hole in the center, then snip in toward the hole with your scissors as shown in the image. Twist the sections slightly to make the blades.
2. Punch two small holes in the top of a full, soda can—one in the center, the other about half an inch to one side. Empty the soda out and pour half cup of water into the can
3. To make the stand, cut a piece of thick foil 8 inches long and 14 inches wide. Fold in half lengthwise, then bend into shape as shown so it fits
across the top of the can. Make a small hole 2 inches up on each side of the stand.
4. Fix the stand onto the can with a small screw. Then push a 4 inches long wooden skewer through the holes in the sides of the stand, threading the wheel in place as you go.
5. Make sure the blades of the wheel are positioned over the small hole in the can. Then put your turbine on a stove burner over a low heat. As the water starts to boil, the escaping steam will spin the wheel on your turbine.
