Take this IQ test : Spot the glass with more water in just 12 seconds


In this puzzle, you’ll see four glasses, each holding different objects like scissors, a paperclip, a rubber, and a watch. Although the water levels look similar, the key is to figure out which glass actually holds more water. The catch? You’ve only got 12 seconds!


Take a close look at the four glasses in the image. They all appear to be filled with the same amount of water, but because each glass contains a different object, the true water levels vary. When the objects are removed, the amount of water left would differ. Your task is to determine which glass has the most water once the object is taken out.




To succeed in this puzzle, you'll need to rely on your problem-solving skills and critical thinking . Focus on the size and weight of the objects inside each glass. Larger and denser items would displace more water, making it appear that there’s less liquid left. Think about how the glasses would look if you took the objects out and visualize the difference in water levels.


If you're struggling to solve this within 12 seconds, here’s a clue: pay attention to the sizes of the objects and imagine how much space each one would occupy outside of the glass. Don’t let the order of the glasses distract you, as that could be a trick to throw you off.


Have you figured it out yet? The answer lies in understanding how much water is displaced by the object in each glass. The larger the object, the more water it displaces, making it look like there is less water in the glass.


For this puzzle, the glass with the smallest object likely has more water, as less water would be displaced.


Congratulations if you managed to solve this tricky puzzle in less than 12 seconds! You might have sharper observation skills than most. If not, don’t worry – keep practicing, and you’ll soon master these optical illusions.
