This is a thing that makes use of 6x Neodymium Csunk ring magnets to levitate a chopstick.
Just something to pass a boring day!


Check out this video:

Build the thing with 10% fill.

*just realised that I'd posted the link to the wrong magnet. The seller actually sent me a diameter 4mm magnet instead of the 3mm. Corrected the link and spec below. Sorry for the blunder :(

Required materials:

  1. 01x Disposable Chopstick
  2. 06x Neodymium Disc Countersunk Ring Magnets D15*4mm hole 4mm: http://www.aliexpress.com/store/product/Free-shipping-30-pack-super-Powerful-n35-NdFeB-Neodymium-Disc-Countersunk-Ring-Magnets-D15-4mm-hole/213181_610756476.html
  3. 01x Staple
  4. 04x M3 screw, flat washer & nut.

Print out the thing.
Attach the magnets using the M3 screws, flat washers & nuts.
Make sure all magnets are facing in the same orientation.
If your chopstick comes with a tapered end, snip it off.
Break off the 2 short ends of the staple.
Force the center portion of the staple into one end of the chopstick, leave about 2mm of it protruding out.
Fit 2 of the magnets through the chopstick, make sure they are in the same orientation as that of the 4 magnets installed earlier.
The magnets I used fit the chopsticks perfectly, you might need to glue them or use inserts if they do not fit.
Adjust the distance of the magnets on the chopstick by trial and error.
Once they are balanced, make an indent on the thing with the staple, this makes it easier to balance the chopstick.

Have Fun! :)

Looks like you are one step closer to the levitating skateboard from Back to the Future!!

Bear in mind, that for best possible magnetic force, the screws should be brass or anything else non magnetic, magnets with a hole don't like to have something magnetic in the hole, they loose strength over time.

Thanks Joakimolsson!
I didn't know about that. Cheers :)
