Now how do I try this at home?!

You don't want to do this at home, floating Oxygen (Co2) is really, really dangerous, for example: if you ever get floating Oxygen (Co2) on your hands or any other body parts, they will freeze with once you get it on you I guess you know what happens if u by a mistake is falling and put your for example hand in from of you, you will loose one hand and have to live with it, you won't die if you didn't mess any of it on your chest witch is mostly impossible, right? Anyhow don't do this at home.
The way he does it is really simple, he make a plastic box can also be metal, he puts a squire of glass in the middle, and then he have a really strong magnet, and a bit of floating Oxygen (Co2)witch does so the magnet can "fly", as you can see on the movie this could be a dangerous try, I would prefer that you eventually seek up a Lab before making any plans to do this.
One guy said that it's one step closer to build a "modern spaceship" do you really think the power of the spaceship would last for that long? I really don't it would last even 5 minutes in the air, in that case they need more military stuff.
I know this has been tried before, but they didn't make it, I've actually been forming some kind of, anti-virus (not the computer way) and seems like i can make it change into a form of magnetic modification, maybe this will succeed one day and maybe i can find a way to bring "flying cars" to the world, I know it's already been made a prototype, but they disagreed to let it go for sale.
So thats why i am trying to experiment with the magnetic power.
Distance from the ground would be "cool" right young boys and ladies?
If anyone have any ideas of what i can eventually do with this experiment here is my mail: Andreasmichaelnordstrand@hotmail.com.
Thanks for reading, I'm crazy that is writing all of this.

Hey Teacher - from hell......I'm Glad your wern't my teacher at school. If you were, i'd think that co2 is like oxygen and be breathing from the exhaust of my car! Doh!

Punkomar: Any space ship created today is modern, because it's being created in the present. Also, we cannot create UFOs, because that's an acronym for Unidentified Flying Object. If we know who made it, then it would hardly be unidentified.
Teacher-FromHell: It's nice to know that Perdition has such a great chemistry program. It's nearly as good as your infernal English curriculum.

Teacher-fromHell: wrong physics principle, this is not due to density.
This is superconductivity. The black chunk is a special ceramic that loses all resistance when cooled to a certain temperature, in this case, it appears to use liquid nitrogen (liquid nitrogen superconductors are somewhat recent, but I saw an equivalent demonstration in my physics II class (college)). With a decently strong magnet (looks like neodymium), the magnetic repulsion from induced currents from simply bringing the magnet close will hold the magnet in place. The magnet can spin because all that is needed to keep the field constant is the position and orientation of the dipole (meaning, north and south). When he pushes it down farther and moves it, the current induced exceeds what the superconductor can carry losslessly, allowing a change in where the magnet is positioned, and since it now requires a current in the opposite direction to pull it away, this counter current allows him to lift the superconductor by the magnet out of the liquid nitrogen, allowing it to cool, therefore losing its superconducting state, and lowering the magnet (neat idea).
By the way, you can actually dip a finger into very shallow liquid nitrogen briefly, the evaporation pushes the liquid away from your finger, so it doesnt touch/freeze it, I have done this (same physics demonstration).

Wups I meant allowing it to WARM.

the thing that comes out the car exhaust is CO2(carbon dioxide) but from the engine is CO(carbon monixide) because of the the platinum piece in the exhaust called the catalytic makes from 2 CO + O2 = 2 CO2

yes and CO is odorless and can kill you. not CO2
