If you enjoy this project, then I encourage you to buy my book, Rubber Band Engineer. It's full of more awesome and original projects crafted from household hardware. You can find it wherever books are sold.

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.


Materials
These are the essential materials, but you could of course add to this list.
Craft sticks, craft cubes, cubes with holes, skewers (less than 1/8" diameter), 10ml luer slip plastic syringes, 1/8" vinyl tubing, cable ties, tape, and hot glue.

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.

<p>very helpful will do in my science project</p>
<p>what i made spical robot hydrulic systemfor science project for kids of class 5</p>
<p>I love to watching this video</p>
<p>Simple and nice </p>
<p>Awesome! Thanks for sharing!</p>
<p>where do you get the cubes?</p>
<p>we are doing this for a project too! long live projects!!!</p><p>#love of school</p>
<p><strong>I made this for my Physics project relating to <em>Pressure</em> 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 <em>sawed</em> it to wooden blocks. Also, the Vinyl tubing didn't fit to the tip of the syringe, so I made a <em>small slit</em> at the end of it and the tube fit in! Thanks a bunch WYE_Lance!</strong></p>
can u tell me in what kind of shop do u get the cubes , stick and the vinyl tubing<br>please its urgent
can i use bolts instead of cubes
<p>Hi,</p><p>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.</p><p>Looks like an awesome project! Thanks for your help!</p>
<p>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&quot; vinyl tubing. Have fun, and please post some pictures if you make any of these hydraulic machines!</p>
<p>when i made i made it, i kind of broke it!!! like that:</p><p>hehehe</p>
<p>Stop Being Smart </p>
And you already said that
it's amazing &amp; helpful for my science project!!!!!!!!!!!
<p>nice to know</p>
<p>Very cool! This will be great for my students. :)</p>
<p>students or &quot;KIDS&quot;?</p>
<p>when i made i made it, i kind of broke it!!! like that:</p><p>hehehe</p>
<p>good enough</p>
<p>were do u get syringes?</p>
<p>can anybody tell me what are those cubes made off in the first thing?</p>
Those are just small wooden blocks. You can pick them up at any regular craft store.
