Tidal Bore

Imagine you're trying to pour a large pot of soup into a narrow-necked bottle using a funnel. Just like the soup gets squeezed and rushes through the funnel, creating a fast-moving flow, a tidal bore occurs when the incoming tide is funneled into a river or narrow bay, forcing it to speed up and form a wave. The connection here is that both scenarios involve a large volume of liquid being constricted into a smaller space, which increases the flow's velocity and creates a noticeable surge—whether it's the soup or the seawater creating a wave.
