The crane will be operated using
two hydraulic syringes. You can see in the
pictures how to set up the syringes using the
connector piece from the cardboard sheet.
Make sure that the thumb rest of the syringe
plunger is held securely within the
assembled connector. You can also attach the
cardboard tabs to the back and the front of
the thumb rest using two pieces of adhesive
tape. Finally, pass the wooden double hook
through the hole in the connector attached to
the syringe.
5
Attach the double hook, together with the
syringe hanging from it, securely to the top of
the crane. Behind this, place a wooden
support into the precut slot provided.
6
Slot two more wooden supports into the
sides of the crane, one from the back and one
from the front.
7
Then attach a 30-cm piece of tube to a second
syringe and fill them both with tap water, as
demonstrated on page 9. Pass the tube
through one of the port holes in the side
panel of the ship, then pass it under the base
panel and then up again, and out through the
hole at the back next to the crane. From
underneath, insert the end of the tube
through the hole in the lowest wooden
support and attach it to the other syringe
suspended from the crane.
8
Pull the tube taut, so that the end of the
syringe is inserted into the hole of the lowest
wooden support. Attach the hook to the end
of the crane using a 10-cm piece of string.
What happens if you carefully press down
the plunger of the syringe at the other end of
the tube?
