1. MAKE THE CAN FURNACE
Time: 1 Hour Complexity: Easy
1a. Using a small knife or Dremel with
a cutting bit, make 3 or 4 U-shaped
cuts equally spaced around an empty
tin can, near the open end (the bottom
of the furnace). Bend the resulting
metal tabs 90° into the can to form
little brackets. These will hold the can
lid later, to make a level platform for
the candle.
1b. Cut another, larger hole in the can
between 2 brackets and opposite
the can’s seam, that extends farther
toward the top. The hole needs to
be big enough to allow candles and
fingers through. Using pliers, bend the
edges of these cuts over, into the can,
so that no sharp edges are exposed.
1c. Cut 2 more rectangular holes on
either side of the can near the closed
end (the top), to allow the light to
shine out and air to flow in. Drill a
hole above each of these, toward the
closed end, that’s just large enough
for the bolts to fit through.
CAUTION: Wear
gloves to protect your
hands when cutting
metal.
