How many saltines can you eat in a minute?

It is difficult for most humans to eat more than two saltine crackers in a minute without drinking. The crackers easily fit into a person's mouth, but they are so dry that they exhaust the supply of saliva, and a dry mouth makes it difficult to swallow the crumbs.

The saltine cracker challenge is a popular food challenge in which a person attempts to eat six saltines in a minute without drinking anything to replenish his saliva. The cracker test is also used to help diagnose Sjögren's syndrome, which is a condition in which a person does not produce enough saliva.
