Explanation:

Subliminal messages in advertising rely on that concept, and is the practice of using words or images (stimuli) that consumers don't consciously detect. It often involves words being flashed on a screen so briefly, we don't detect them.

Here we have baking words in the top of crackers - this is a hidden message which is meant to act on a subconcious level of the consumer.
