OEGSTGEEST, Netherlands -- Strap on 3-D glasses and watch holograms of cartoon sperm sprinting to fertilize an egg. Climb inside a gigantic nose, enjoy the smell of fresh hay, then feel the wind blast on your neck when it sneezes. Walk across a bouncy rubber tongue complete with taste buds and realistic burping noises in the background.
