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!

I made this for my Physics project relating to Pressure and it came in handy! It was simple to make and yet demonstrates the topic in the most easiest way to understand. I took a wooden stick from my attic and sawed it to wooden blocks. Also, the Vinyl tubing didn't fit to the tip of the syringe, so I made a small slit at the end of it and the tube fit in! Thanks a bunch WYE_Lance!

Hi,

I'm hoping to do this project, but I was hoping you could provide some specifications about the syringes and vinyl tubing. I see you used 10mL syringes, but what kind of tip do they have? And what size tubing did you use? The links provided aren't taking me to the right source. I want to be sure they'll fit together correctly.

Looks like an awesome project! Thanks for your help!

Hi, thanks for letting me know about the broken link. I fixed the materials link. You should get 10ml luer slip plastic syringes without needles, and 1/8" vinyl tubing. Have fun, and please post some pictures if you make any of these hydraulic machines!

Those are just small wooden blocks. You can pick them up at any regular craft store.
