Instructions for Jaws of life school project for Grade 7 Step by Step

• Step 1: Cut out the three cardboard pieces as shown i.e. two for the arms and one rectangular piece for the base.
• Step 2: File down the top end of the small syringe and then drill a small hole through the plastic part at the top end.
• Step 3: Drill holes at each end of the ice cream sticks. The holes must be sized such that you can get a bolt and nut through them.
• Step 3: Attach the small syringe midway to the rectangular cardboard base using hot glue.
• Step 4: Wrap the base with duct tape and use duct tape to further secure the small syringe to the base. Wrap the arms with duct tape.
• Step5: Attach the arms to the base with one bolt and nut each. Tighten to the point that the arms can still move freely.
• Step 6: Attach the two ice cream sticks to the top of the small syringe using a bolt and nut. Attach the other end of each ice cream stick to the left and right arms. All parts must be tightened to the point that they can still move freely.
• Step 7: Fully depress the small syringe and the arms should be in the closed position.
• Step 8: Attach a tube to the large syringe and fill the tube and syringe with the red-coloured water avoiding any air.
• Step 9: Now attach the other end to the small syringe
