In Acrobat you can't - it's done by building the entire document as a Flash file (which may or may not end up inside a PDF). You can do a basic page turn effect with InDesign CS4 via the SWF export options, but to recreate the same thing in a normal PDF is not possible, as PDF pages by definition are always flat on screen.
Many people have devised the necessary math and animation sequences to do it in Flash, there are tutorials online and multiple service providers who'll convert documents for you. Building the effect by hand in Flash is not a novice project as although the visual concept is simple, the Actionscript needed to control all the possible mouse events is a nightmare.
It's important to remember that by turning a multi-page document into SWF and re-embedding it into a PDF, you'll lose accessibility in a big way. Acrobat's search box won't work, multi-page printing via the menus won't work, and so on. It might look good, but it rapidly annoys people.
