Consider an Orangina bottle: shaped like an orange it is designed to look like one. But it does so in a very primitive way. Imagine the product is the packaging. Wouldn't it be great if we could grow Orangina bottles?
It is not hard to imagine that genetic technology makes it possible to grow oranges with a hard plastic skin. In additon, oranges can be modified to produce enzymes which degrade the flesh of the orange resulting in a self-generated juice... better than the real thing!
