Great video!! I'm gonna try it. Just out of curiosity, is your voiced processed?

Yes... well sort of... he records his voiceover and alters it to prevent Feds from tracking his voice using recognition software.
i honestly did not expect the voice to garner that level of mockery.

NurdRage- I think this whole presentation is very creative, well done!

magnet roads, specially designed pencil lead like cars, i see the future

If thicker pencil lead wont work then there must be a surface area effect going on , maybe some thin films like plastic might work.

Was wondering how to levitate an array of these leads - maybe gluing several parallel, but separate, to a thin tissue of some sort. how would the fields of leads in the array interact?

So what specific brand(s) of pencil lead have worked for you and which ones defiantly don't?

I also saw this levatating magnet in Simon Queenfield's book Gonzo Gizmos

Tried this with 8 1cm. diameter neodymium magnets and a piece of 0.3mm. pencil lead. It seems to work but the levitation is very very small. Less than 1 mm. Will try it in water next.

also works with beryllium, bismuth, carbon, copper, mercury, silver, and zinc.

sorry, i havent tried. its just that those are all the diamagnetic elements, so i just assume they would work. i thought i had seen a picture of bismuth, but i forgot where.
oh i see. It doesn't work with all diamagnetic elements. because the effect has to overcome the mass of the object. But since all of those elements have different densities, and thus masses for equal volumes, most of them won't work. You need REALLY powerful magnets to get them going. Pencil lead and neodymium magnets are the easiest to get things that this has a visible effect on.

Levitation of a magnet can be done with all of these materials. I've even seen it done with fingers, fingers are mostly water, and water is diamagnetic. You have to use another magnet to counteract most of the weight though.

that does make sence. that explains why all the diamagnet images on google had large electromagnets.

Modern pencils contain graphite. Thin graphite surfaces can levatate above magnets. Try getting thin graphite squares from a home depot or lowes because I am pretty sure they have them.

Hi, cool i have watched youre videos in youtube for some time now, i didnt know you had an account on Instructables, hehe cool videos, i like chemestry but im just an amateur.... keep up the good work.
This little device http://www.kjmagnetics.com/proddetail.asp?prod=LEV2 works pretty nicely. It uses the more traditional technique of suspending a magnet between sheets of graphite, with another magnet "helping" to counteract the weight. Interesting that pencil leads can have the appropriate type of graphite...

I always wondered why that happened... Thanks for the explanation.

Very cool! I was going to see how you were faking it but ITS REAL!
This is a 'must try' experiment !
You've used an HB lead. It's probably worth trying with a 2B (softer - higher graphite content) to see if it levitates higher.

Awesome demonstration! Newly, thanks for the captions in the video.
