Next, sandwich the handles on either side of the
syringe between two wooden supports; slide one
along the barrel of the syringe until it’s in front
of the handles, and slide the other over the
plunger behind the handles. Pass a wooden
rectangle with two hooks through the connector.

Insert the two wooden panels into the back of
the underwater reef.

Then attach the reef and the wooden panels to the
base panel that goes with them. Insert the two
pieces of coral into the precut holes in the base
panel.

Put your scissors mechanism in place on the base
panel. The sea monster should be pointing to the
left. Make sure that you set it up as shown in the
close-up pictures.

Your Giant Snapper is now ready to be used!
Carefully press the plunger of the full syringe
down and watch what happens! Have a go at
snapping at Pepper in the diving chamber!
Tip!
The connector must be in a vertical position. Y
ou
can gently turn the plunger in the syringe until it’
s
pointing in the right direction. If the conne
ctor isn’t
gripping properly, you can attach it more s
ecurely by putting
two pieces of tape on each side of the plunger
’s thumb rest.

WHAT’S
HAPPENING
This time, you’ve linked your hydraulic
system up to a mechanical system. As
the plunger moves, it extends the
scissors mechanism, causing the scissor
joints to close and move upward. You’ve
used a simple movement (pressing
down the plunger) to trigger a more
complex movement. Genius!
