I've just read an article. Yes, the solid propellant can't make the rocket reach space. It need hundred solid propellants for reach space. But, if i choose the liquid rocket propellant, it will blast off until space.
Is it true?

Maybe if you had a couple of million dollars to play around with it could happen.

If so... How many the maximum altitude of my bp rocket?
And, where altitude that have zero gravity?

If you BUY some potassium nitrate which is 99.8%-99.9% pure, you might get ~100m(?) max. :-\ But I'm just guessing because I have no idea how big your rocket is and how on earth you are planning to make it.

Space = zero gravity

Probably somewhere way outside the Solar System!

You can't get zero gravity anywhere in the universe - it's everywhere, to a greater or lesser degree.  What you can achieve though, is free-fall.  You can get short-term free-fall by using a sub-orbital parabolic flight, as with the 'vomit comet' astronaut training flights, or by achieving orbit.  For a low Earth orbit, I think your rocket will need to achieve a speed of around 8 km/s by the time it reaches its orbital altitude.  You'll need to be able to control the flight somehow too.

If you do manage to get something up in to low Earth orbit a lot of people/countries will be very annoyed with you unless you're doing it as part of an officially planned and sanctioned program; you'll not only be adding to the huge amount of stuff that's already floating about up there but also risk damaging someone else's stuff, not to mention the risk of being though of as a potential terrorist.

Do you think $10000 to $100000 or so is cheap?

If they could have done it for less they would.
Do you think you can do better?

I don't yet to watch that video. But, is rocket that reach seven meter tall without payload? Is it  full filled by fuel?

You might want to look at the photos

But it's sure as hell not gunpowder.

The rocket was equipped with a $20,000 solid-propellant motor, which is the largest built by amateurs. The motor was to launch the rocket into space just 15 seconds, after obtaining speeds as fast as Mach 5.

Doesn't it get burned with Mach 5 speed!!!?

That might be why it didn't work in 2002. I doubt it though.

Zero gravity = space
near zero gravity = DEEP space (not just in orbit)

Free fall OR orbit?

I'm not sure I understand your question SC.  You'll be in free fall in orbit.
