    Use the syrings as the hydraulic cylinders. The large syring is the operater the small one is the one you attach to the cardboard which you have fabricated a pair of sissors. The small syring you attach to the handle. Attach body of syring to one handle and the plunger to other handle. Hook up tubing between to syringes that you have filled with water that you have colored with food color to represent hydralic fluid. As you move the large syring it will cause the other syring to move like in a hydralic system. If the 2 syrings are small and large like one is half the size it will be a 2 to 1 ratio and small will have twice the power. Good luck.

How do i make a jaws of life model for a school project - with syringes and cardboard.

You first need to see how they operate. If you can visit a fire station, perhaps they can explain how they function. You might also want to contact Hurst Tools for some assistance in understanding how they operate.

These are hydraulic tools, and once you understand where the actions points are, you should be able to construct something that will work in a limited fashion. Here is their website address: There is a contact link at the bottom of the page.
