Let's break down the logic: Visual Illusion: Although the water levels appear identical in all glasses, each glass contains an object of a different size. Displacement Principle: When an object is placed in water, it displaces a volume of water equal to its own volume. The larger the object, the more space it takes up, leaving less room for actual water. Logical Deduction: If you were to remove all the objects, the water level in the glass with the largest object would drop the most. Since the paperclip has the smallest volume, it displaced the least amount of water, meaning that glass contains the highest volume of actual water. Stay Sharp Tip: This challenge trains your brain to "see through" surface data and find the underlying truth.
