This was on my mind for a long time, to try and balance two circular objects on top of one another and I did it !!!! Yeah, it did take 45 mins of concentration and no movement (not even vibrations/sound/walking/heavy breathing etc. etc.). The supporting object is a tennis ball and the object on the top is a circular rubber globe that I picked up as a freebie. These are the kind of things that really make you happy, the centroid of the bottom object and the top object on the same line and hence, the perfect balance.

really AMAZING!!Hope you have not used Fevicol!
really great…seems like me and ur dad think alike
believe u but…since i know tht u would spoil a tennis ball for anything…
I guess simply aligning the centroids of the two objects is not the reason for this ‘perfect balance’. There is a third object involved in this case - the floor/carpet.
My 2 cents
Well, it just eased my problems a little bit because I did not have to concentrate too hard on trying to prevent the bottom ball from moving, also the top ball being a lighter than the bottom ball did help too.
But it is only because of the centroid alignment that they managed to stay the way they are.
And all you non-believers , no glue used
And to add, my record were influenced by this and this.
