At first glance, this looks like an easy question. Just look at the four glasses and decide which one appears to have the highest level of orange juice.

But there’s a catch: the glasses aren’t all positioned or shaped the same way. 😏

So before you answer, take a second look.

🥤 Glass A

Glass A is standing upright and appears to contain a good amount of juice. The level looks fairly high, but the glass is also relatively wide.

🥤 Glass B

Glass B is taller and narrower, and the orange juice appears to reach quite high inside the glass.

That can make it look like it contains more—but the height of the liquid alone doesn’t tell us the volume. A taller, narrower glass can hold less than a shorter, wider one even when the liquid level looks higher.

🥤 Glass C

This is the tricky one! 👀

Glass C is tilted, which makes judging the amount much more difficult. The liquid surface remains level because of gravity, even though the glass itself is leaning. Tilting a container can dramatically change how high the liquid appears without changing the amount of liquid inside. (Mathematics Stack Exchange)

So don’t automatically assume that the glass with the highest-looking liquid level has the most juice.

🥤 Glass D

Glass D is upright and appears to have a very high juice level. At first glance, D looks like a strong contender for the winner.

And that’s where this puzzle gets interesting.

🤔 So Which One Has the Most?

My guess from the picture is D! 🍊🥤

But there’s an important catch: a photograph alone cannot establish the exact volume unless we know the actual dimensions and capacity of each glass.

The amount of liquid depends on the three-dimensional volume of the juice, not simply how high the juice reaches. This is why the classic “tall glass versus short glass” puzzle can be deceptive: changing the shape of a container can make the same amount of liquid look very different. (gauthmath.com)

In fact, even calculating half the volume of a tapered glass isn’t necessarily as simple as putting the liquid halfway up the glass—the changing width of the glass matters. (Mathematics Stack Exchange)

🧠 Don’t Trust Your Eyes Too Quickly!

That’s what makes this such a fun brain teaser.

Our eyes naturally focus on the height of the orange juice, but height isn’t the same thing as volume.

Think about pouring the same amount of juice into two completely different glasses. In a wide glass, the juice may look shallow. In a narrow glass, exactly the same amount could reach much higher.

The amount hasn’t changed—only the shape of the container has.

And Glass C adds another layer of confusion because it’s tilted. 😄

🍊 What’s Your Guess?

Before looking at anyone else’s answer, choose one:

A 🥤
B 🥤
C 🥤
D 🥤

👀 My pick: D

But would you agree?

Look closely, make your choice, and don’t change your answer! 😂🍊
