This visible puzzle demands lateral thinking, or what we call “thinking outside the box.” To arrive at a solution, you ought to think carefully according to the data in front of you.

In the photo, there are four glasses full of water that appear to have the same level. Each of them contains a unique item of different sizes and weights.

You need to figure out which glass has the largest amount of water compared to the others. Well, if you’re one for challenges, take a moment to ponder before scrolling down for the answer.

Need more time? No worries, take another sip of coffee and think. The glass that appears to hold the most water—despite the visual trickery of differing items—is revealed at the bottom. Ready for the big reveal? Here it comes!
