Welcome to Cookie Physics, where the laws of thermodynamics are as sweet as they are sticky!
The Cookie Second Law states that heat is always transferred from hot cookies to cold cookies, and that this process is always accompanied by a transfer of deliciousness. This is why cookies always seem to find their way into the most unlikely of places, like the bottom of your shoe or behind the couch cushion.
