The tricky water puzzle that’s confusing almost everyone — can you solve it correctly?

At first glance, this looks like a straightforward visual puzzle designed for children, but in reality, it has confused thousands of people online. Four identical glasses are placed side by side, each filled with water up to the same visible level.

Inside each glass is a different object, and the challenge is to determine which glass actually contains the most water. What makes this puzzle so interesting is that the answer is not based on what we immediately see, but on how we interpret space, volume, and physical displacement.
