Dancing with 10 Bottles Balanced on One's Head

i don't know, it seems like you would need a ladder to stack up all those bottles

I have seen this sort of act before. It takes skill and showmanship. On the other hand, I bet anyone of us could balance the ten bottle stack on our hand with a little practice.

Try it with a broom and see how long it takes. One you can do that, put the broom on your head. There, see what I mean?

Probably glue hehe.

What are those white things on the bottom of the bottles?

after effects, motion tracking. videocopilot.net is a good place to learn about motion tracking if you don't know what it is.

notice once she places the bottle on her head the highlight on the bottom no longer "moves" with the contour of the bottle as the sun hits it.
