Michael, Elizabeth, and I made a table-top sized Van de Graaff generator.

Step 1: Materials

This is what you need:
     • 1' long 4" diameter PVC tube
     • 5" long section of 1/2" CPVC pipe
     • 1 airplane blanket (or other static material like rubber of fleece)
     • Metal Bowls
     • Scraps of 2x4
     • Motor
     • Dowel (lots of dowel)
     • JB Weld (I now love this stuff)
     • Hot Glue
     • *Optional* a ball bearing for shoving in a hole
Also, 2 friends insane enough to do this with you!

doed anyone know how to make a discharge wand. I am confused.
Would you give more info about the motor which you used, such as Torque value, Power, Brand name (if possible) etc. ?
you are very intelligent and smart boy, I love you..................!
looks like he has a G.F :D <br>
elizabeth kawaii!
(or other static material like rubber &quot;of&quot; fleece) <br>don't you mean or ?
Hey,<br><br>Would some old grey plastic guttering do as the pole that holds it up i think it is PVC or possibly U-PVC
NIce little VDG, in the spring the garden centers will all have small stainless garden gazing balls, these make great collectors, and under 12&quot; diameter they are pretty cheap!
Wow, that's actually an excellent idea! I always thought those were only made of glass, but Google is your friend I guess :D
MIne uses a 12&quot; stainless one, very efficient, they are also online<br> <br> <a href="http://www.sears.com/shc/s/p_10153_12605_SPM678183501P?sid=IDx20101019x00001a&ci_src=14110944&ci_sku=SPM678183501" rel="nofollow">http://www.sears.com/shc/s/p_10153_12605_SPM678183501P?sid=IDx20101019x00001a&amp;ci_src=14110944&amp;ci_sku=SPM678183501</a><br> <br> <br> <br>
I want one
yes hello Elizabeth you can cut on my pipe anytime
I have lots of questions.<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Do you have to wrap the rollers with conductive or non conductive material<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *How many RPM is the motor<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Do you attach 2 metal combs to the top and bottom of the airplane blanket<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *Do the metal comps touch the airplane blanket<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Does it matter which side of the airplane blanket is attached to the combs<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*If you make it 3 1/2 ft tall, will it be safe to touch it still<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Do the combs attach directly to the discharge in the inside<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*I think I saw the motor attached to an outlet, do you keep&nbsp;the current at AC, or do&nbsp;attach a regulator to it<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;* and, does the top roller move, or stay still<br /> <br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I am&nbsp;sorry for all the questions. The Instructable is great though!&nbsp;&nbsp;
And I have a lot of answers:<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; Non-Conductive<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; Mine is 3450, the faster the better, but keep in mind that it needs to have some tourque<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; They don't attach, they just almost touch it<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; See previous answer...<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; ?<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; It'll just hurt like all hell (really? i want pics!!!)<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; Attaching them to the outside is easier, but inside is better looking, and yes<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; The motor is really a small part, many would work. I chose an AC motor because it was the easiest<br /> &nbsp;&nbsp;&nbsp;&nbsp; &bull; It can move if you want (or put a tube around a tube and make less friction), we just chose to keep it static<br /> <br /> I don't mind at all, I'm more than happy to answer any question if you are nice.<br />
will a 2900 rpm motor work?<br>
Nice Job!
Does it make sparks?<br /> <br /> Can you do the <em>dancing monks</em> trick?<br />
yes and ??? dancing monks???<br />
Stand a line of people on insulators (plastic stools, in buckets etc), all holding hands and with one person touching the dome as it runs.<br /> <br /> They all get charged, until the person at the other end of the line touches &quot;ground&quot;, at which time they all get a shock.<br /> <br /> It was first done to a line of monks that was connected to ground, and then the first monk touched the ground of a charged Leyden jar.<br /> <br />
We did this in a Phyics lesson at school just last week... other fun things to do include: <br>- lighting a bunsen burner (or similar) <br>- making someones hair stand on end <br>- dropping feathers, then having them stick to the charged dome, then becoming attracted to the nearest neutral object (similar to how a balloon sticks to a wall after being rubbed on something) <br>- shocking someone just for fun <br>- producing mini lightning
i think i saw that on brainiac...
cute girl =)
Well Hello Elizabeth!<br />
