I've built this Van De Graaff generator for a science coursework and it works pretty well considering it being built in a rush (needa hit that deadline man). With it, I managed to achieve a 1.5cm spark, a happy physics teacher and full marks for my coursework :D.

All the parts used are easy to find in shops and really cheap. Don't be too intimidated by the looks of it, its not that hard, improvising is key.

It's my first instructables so bear with me and I welcome any suggestions and comments.

All the best!- CCX

Safety
A generator is able to generate a very high voltage but it's pretty safe due to the low current. One with a weak heart, a pacemaker or any sensitive electronic device should not be operating or even be close at it. I bare no responsibilty over your carelessness and injury.

Step 1: Understanding How It Works.

It is really important to understand how it works, if not what's the point?

A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels.- wikipedia

Understanding it can really assist on your build. (I missed this part)

<p>How did you connect the bottom teeth to the top?</p>
can i use any other material for wheels<br>
<p>Yes by refering to the triboelectric series accordingly in step 4</p>
Great instructible! The only thing you I think you should try is changing the belt material. I've read that elastic bands(like exercise resistance bands) work very well. Hope this helps.
Well.. I wanted to get them but they are very costly here...
<p>awesome. i made one when i was younger. i always had a hard time finding suitable belt material. </p>
<p>Awesome! Very simple design!</p>
<p>Look at this guys :-)</p><p>https://www.youtube.com/watch?v=7qgM1A3pgkQ</p>
<p>Awesome! Great job!</p>
Extremely easy but awesome build :D
Excellent work !<br>Thanks for sharing.
<p>What does the bottom brush connect to? It looks like the bracket under the bottom plywood has a wire going to it?</p>
<p>The bottom brush connects to Ground, in this case the negative (black) terminal, see photo in Step 8.</p>
<p>Woow! Very good ideas in this project. Try it harder and improve it... I stay tuned!</p>
<p>Interesting build using unique parts. Nice engineered payout. Obviously improvements can be made, but for what you had to do in little time, it looks really good. </p>
<p>Awesome! I always wanted to make my own Van De Graaf generator. Thanks for sharing the plans.</p>
