Introduction: Easy Hydraulic Machines
In this Instructable, I'll to show you how to build many projects that use a simple hydraulic system that kids in elementary school can build. Each step will show you one of four machines that use the same basic mechanism.

First thing's first: How to make a hydraulic system
Step 1: Simplest Machine
The video gives you an overview of the simplest hydraulic machine - the photos tell you how to build it! I've had kids as young as 1st grade build this project.
Step 2: Hydraulic Box
The hydraulic box is more challenging to build.
Step 3: Hydraulic Drawbridge
The hydraulic bridge project was originally conceived by a student named Daniel H.D. Thanks Daniel!
Step 4: 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!
