Now the second time I've seen this posted and feel like stating what I think is obvious, but clearly isn't.
Although the computer controlled ball is cool, and has lots of uses; it is no more "defying gravity" or "levitating" than a hot air balloon or rocket!
A force greater than that of gravity is being applied to the ball, thus countering the effects of gravity. Whoop dee doo! The control element may be smart and "new", but making a big ball baring move with a magnet is hardly ground-breaking.
Is it just me, or is this "revolutionary" floating ball, slightly less amazing than watching paint dry?
Jeeze! What I just wrote makes me sound like an uptight loser with a grudge. I didn't mean it that way. I just think the coverage of this "modern marvel of engineering genius" is a might bombastic.
