How to
make an
Archimedes
Screw
Use a compass to
make neat circles.
Cereal box card board is perfect for making
Archimedes Screws.
Use the compass to
draw a circle that is
a bit smaller than
the diameter of the
center support tube.
Cut out the outside circle then cut
toward the center to cut out the inner
circle.
Tape together
each ramp after
butting up the
ends.
Cut the length of the tube so that
you are able to collapse it.
Insert the tube into the “slinky”
of circles.
Stretch out
“slinky” so
that the
ramps are
evenly
spaced.
Wrap the screw in plastic, paper or
insert it into a 2 liter bottle.
