The Wooden Hydraulics Machines Kit Set from ThinkGeek is actually 4-kits in one, as you’ll be able to “build a: Scissor Lift, Platform Lifter, Cherry Picker, and Excavator.” Available now, priced at $29.99. Video after the break.

Each kit is easy to construct and uses syringes (minus the needles) and tubing to provide the hydraulic push.
