This project is easy to build, and it allows young engineers to get hands-on experience with the power and delight of a hydraulic-powered mechanism.
For easier facilitation, you can fill the syringes with air instead of water. An air pressure-powered systems are called pneumatics.

Plastic syringes, tubing, & adapters that can replace cubes the holes
Step 1: Hydraulic Box
The hydraulic box is more challenging to build.
Step 2: Hydraulic Drawbridge
The hydraulic bridge project was originally conceived by a student named Daniel H.D. Thanks Daniel!
Step 3: Hydraulic Fortune Teller
The hydraulic fortune teller uses the same mechanics as the Judobot to achieve 3-dimensional movement, however this project is easier to build because it doesn't need to be thoroughly designed to battle. I like the idea of a fortune teller, but the face can be replaced with other things to create a variety of projects: a catapult arm, a serving basket, cannon.... be creative!
