There are word games where you can lead smart (presumably) humans to answer a question incorrectly by biasing them with words rhyming with the wrong answer beforehand.
Can you hide information in the absence of a vector? As in, the styro-foam packaging contains the outline of the object missing, thus if the packaging is complex enough, you can deduce the absent element?
