old Pepsi commercial?

Did anyone see this commercial where the guy goes on the rollercoaster with the Pepsi, and it doesnt spill it going through all the inversions? And then when he gets off, he looks at some sexy girl and spills it.

Does anyone know how they did this? It would be really cool if he actually did this. What special effects did they use?

That's what I thought, but after he goes on the coaster, he goes to drink the soda and it all spills out.

Stop camera, shoot scene of hot girl, start camera replace glued pepsi with real pepsi - if you notice, you only see the girl for one shot. Thats where they switch.

And by the way, the coaster was Alpengeist
