My finished hydraulic system

Me and my group have finally finished our hydraulic system.  The finished model now has a platform for the pebble to hold on. The platform is held by one string that is attached to the crane. The crane can now move small objects to a different place. Our crane goes up and down and rotates left and right. There is no water in the syringes, so now we know that we finally finished it. There was supposed to be water in the syringes, but the crane still works without water. We also managed to make the front part of the crane higher by adding two more Popsicle sticks to the crane. Here is a picture of the finished model.
