Step 11: Where to go from here.

Do you have questions, comments, improvements?  Let me know in the comments below.

I was thinking about where the tornado machine should go from here.  I have yet to design a  tornado machine 2.0 but if I do I would like some of the following.

-RGB LEDs and a micro-controller to choose precise colors for every occasion.
-Larger components.  Powerful, high speed motor and custom laser cut impeller.
-Better looking base/housing.  Probably made from clear lexan. Because I am familiar with shaping and molding this material.
-Micro-controller programmed to vary the "weather".  Could be set up to vary the speed of the motor quite easily by using a high power transistor and a bit of code.

These are just some of the improvements I thought of, let me know what you build or come up with.

<p>Can I make a Tornado machine with a little shaft like one of these small motors?</p>
<p>I am currentely in 9 standard and this seems some thing tough for me</p>
I have a idea for one that I may make with a fish tank and I could put the motor on the top so it will create a updraft not a downdraft like yours and this is my inspiration keep up the good work :)
awesome idea though I built it a little bit diferent by using a pop bottle instead but still works great<br>
<p>I'm glad you liked it enough to build one of your own. Some of my earliest versions were made with 2-liter bottles and they worked great. Nice job!</p>
beautiful, should bother no one my friend, my sons are about to have a blast with it!! I have made a whirpool machine with a tesla turbine made with cds and magnets, but it is complicated, a child could make this one on his own and have lots of fun , and learning with your led power calculation without forggeting myself as well!!, thank you for sharing,
cant wait to try this out
I love the dollar store fan idea.
Thanks. It makes it a simple and more accessible project for anyone.
There is nothing &quot;technical&quot; about calling it a whirlpool. There is no such thing as a tornado in water. By calling it that you're misleading people and teaching them the wrong thing. When someone is taught the wrong thing someone else later on has to &quot;un-teach&quot; them the false information you're feeding people. So please, call it what it is. I have a motorbike at home, but if you want to be technical then you can call it a car.
Quite obviously this is not a pool and 95% of all whirlpools don't whirl but bubble. <br>Hope you never end up in a plasma lamp store... <br>
For years they sold an adapter to connect two soda bottles together and create a [water] tornado in a bottle. Also, they sell novelty [water] tornadoes that has an image of a farm and cows on the outside of the cylindrical &quot;globe&quot;. Yes, it's actually a whirlpool, but the effect looks like a tornado, and is the easiest way to show a child what a tornado looks like, hence, has been called a tornado for years [for demonstration purposes].
When I was a kid my dad and I used to make these, he always called it a tornado machine. He passed away when I was younger and I have called them by this name ever since. Sorry if that rubs you the wrong way.
Good work, but it would be safer to use a magnetic stirrer system. It would present its own challenges but water and electricity shouldn't be one of them.
Hi hi :) <br>Numerous questions :) - Is it possible to find or source an underwater motor as opposed to potentially sustaining leaks in the near future? <br>What additive could be added to the water to prevent the water growing algae? <br> <br>I'm thinking longetivity :)
If you set it up like this instructable shows it should be fairly waterproof. But I suppose for extra protection you could tape the holes in the electric motor and dip it in wax to give it a waterproof coating. This will cover the vents of the motor that are normally used to cool the motor, so it may not be the best solution but I couldn't find any cheap, small, waterproof motors online. <br>Most of these small cheap motors will take a fair amount of abuse though. I am using a 3 volt DC brush motor and have run it at up to 15 volts for a few minutes with no problem. Also purified/distilled water by itself isn't terribly conductive, so if the motor gets a little wet at some point it likely wont hurt it. As far as keeping the water from growing algae, maybe a drop or 2 of bleach or vinegar added to the water will help. I haven't tried additives in the water because it is somewhat trivial to unscrew the top and just replace the water, but you are welcome to try. Remember only a drop or 2 as bleach tends to cause havoc with certain metals.
I think this would look cool if you used UV leds and a UV liquid that is easily made by following this instructable: <br> <br>http://www.instructables.com/id/Create-Homemade-Fluorescent-Black-LightUV-Display/ <br> <br>What could be more fun than a glowing tornado?
All I can think of is dropping Monopoly houses into the mix....:-)
.. And some lego men! <br>
agis68, it's true I could use the RGB leds that cycle the colors. I like that Idea, I just might try that.
you can build it with RGB leds without the m/c to save some space. Of course you will have a periodic cycle of colours
It's a twister! It's a twister!
nice <br> <br>a project for the kids during the coming holidays ! <br> <br>thank you !&hellip;
Thanks WriterChick. <br>Mad_b, I have seen those before too but I have never made one.
There is an option that (I've made a prototype once) works well too, like professional stirrers do; in a few words, you can attach a strong magnet on the motor shaft. Then you position this on the bottom of the jar (normal position, glass in the bottom). Take a cylindrical magnet and put inside a plastic tube. Drop this tube inside the jar; when you turn the motor on the magnet in the shaft will make the magnet cylinder inside the jar to turn, creating the tornado as well. :-)
This is lovely, complex and well-detailed 'ible. Thanks for sharing, and congratulations on breaking the &quot;no documentation&quot; jinx!
