Maglev Car

this is a video of my science fair project, i thought i would post it...it is a car that is being levitate soly due to the power of repelling magnets, the black things you see are the magnets, this car levitates about 2cm off the track, and i am currently trying to make a propulsion system by only using permanent magnets. the car is made out of foam and the blue stuff your see is double sided sticky tape to make it more aerodynamic.
*NOTE* if you saw this video on youtube, that was mine...and the picture credit goes to this site it is not my image...just wanted to point that out...
