We had used 6 years of our life to discovered this. We have to see how powerful the magnet should be to lift the car to the right height. Finally, we had the idea of using plasma power and magnet power.
When we constructed the thing, it took us many tries to make the thing works. After all those tries we tried to fix the magnets and plasma engines for it to work more powerful. Then the car lift up. That was our first flying car and we called it jet cars
