This popular optical illusion has been confusing people all over the internet. At first glance, the four glasses appear to have very different amounts of water. Glass A has a wide bottom, B has a narrow top, C is tilted at an angle, and D looks straight.
So which one has more?
The answer is: All four glasses have exactly the same amount of water.
It’s a clever trick that plays with our perception. The different shapes and angles make our brains think the volumes are different, but they’re actually identical. A great example of how easily our eyes can be fooled!
