- Use the nail to punch two small holes in the top of thefruit juice
can. The holes should be on opposite sides of the top, about l/4 inch
from the edge.
- Pour all of the fruit juice out of the can (maybe you’dlike to take
a juice break at this point). Remove the paper label, then rinse the
can out with water as best you are able.
- Plug one of the two holes (either one) with a sheetmetal screw. And
that’s our water boiler.
- Now carefully remove the bottom of the soup can witha can opener,
and set it aside.
- Using a pair of tinsnips, cautiously cut along thelength of the can
and flatten out the metal. Look out for those sharp edges.
- From the flattened metal, cut out a strip about 4-l/2 inches long
and l/2 inch wide. Again, work with care.
- With the finishing nail, hammer a hole about l/4 inch from each end
of the strip and one in the very center.
- Carefully bend the strip into a square-cornered “U” bracket. The end
holes in the strip must line up opposite each other. Make the bottom
of the “U” about l/2 inch wide.
- Take the lid you set aside earlier and punch a smallhole in
the exact center. The hole must be large enough so that the lid spins
freely on the finishing nail.
- Make eight equally spaced “pie” cuts into the can lidas shown in
the drawing.
- Gently bend the cut sections to create an eight-bladedturbine wheel.
- Using the finishing nail as an axle, assemble the faninside the “U”
bracket.
- Locate the bracket on the can so that when steamshoots from the opening,
it will hit the flat part of the blades. Now mount the bracket on the
can with the other sheet metal screw. To keep the turbine wheel centered,
wrap some tape on the axle on both sides of the wheel.
- Fashion a simple support stand out
of the coathanger, as illustrated. The stand must support
the juice can about four inches over the open Sterno can.
- Use the eye dropper to fill the can about l/3 full withwater.
- Light the Sterno and place it under the boiler. In a few minutes,
the water will boil and steam will spin the turbine.
