The answer is a hole. A hole gets bigger the more you take away from it, because removing material (dirt, fabric, metal) around the edges only makes the empty space larger. It’s one of the most popular riddles in English, and the reason it stumps people is that we instinctively think of “taking away” as making something smaller. With a hole, the opposite is true.
Why the Answer Works
A hole is defined entirely by absence. It isn’t a thing you add to; it’s a thing that grows when stuff around it disappears. Dig more dirt out of a pit and the pit expands. Cut more fabric from a tear in your jeans and the tear widens. The “taking away” doesn’t shrink the hole because the hole IS the taken-away part.
Mathematicians who study shapes and spaces (a field called topology) actually classify holes into distinct types: cavities like a pit in the ground, openings like a tunnel through a mountain, and enclosed spaces like an air pocket in Swiss cheese. All of them share the same core property that makes the riddle click. They’re defined not by what’s there, but by what isn’t.
Variations of the Riddle
This riddle shows up in dozens of forms. Some swap the phrasing while keeping the same answer:
- “I weigh nothing, but you can still see me. Put me in a bucket and I make it lighter. What am I?” Still a hole. A hole in a bucket removes material, making the bucket lighter.
- “The less I have, the more I am. What am I?” Same idea, tighter wording.
If you’ve played God of War Ragnarök, you might recognize it. The character Mimir poses this riddle during gameplay, and it’s become one of the more talked-about puzzle moments in the game.
The Concept Beyond the Riddle
The “gets bigger when you take away” idea isn’t just wordplay. It describes real phenomena across science and everyday life.
In the lungs, a disease called emphysema destroys the thin walls between tiny air sacs called alveoli. As that tissue breaks down and disappears, the small sacs merge into fewer, much larger air spaces called bullae. You’re literally taking away tissue and the空 spaces get bigger. The tradeoff is devastating: that lost surface area is what your lungs use to exchange oxygen and carbon dioxide, so breathing becomes progressively harder.
Wound care follows a similar paradox. When doctors clean a wound by removing dead tissue (a process called debridement), the wound often looks bigger afterward. The dead tissue was masking the true size of the injury underneath. Clearing it away exposes more raw surface, but that’s actually the point. Dead tissue blocks new blood vessel growth and prevents skin from regenerating. Removing it resets the healing process, allowing healthy tissue to start filling in from a clean foundation.
Even weight loss works this way in a sense. After someone loses a significant amount of body fat, the skin that stretched to accommodate that fat doesn’t snap back. The result is loose, sagging skin on the arms, abdomen, thighs, and chest. You took away volume from the body, but the visible envelope of skin appears larger and more prominent than before.
Why This Riddle Is So Effective
The reason “what gets bigger the more you take away” is one of the most enduring riddles in any language comes down to a single cognitive bias: we associate “taking away” with reduction. Our brains default to thinking in terms of objects, and objects shrink when you remove pieces. A hole isn’t an object. It’s the space left behind when the object is gone, which means every rule about addition and subtraction flips.
There’s actually a well-documented psychological parallel here. When people try to suppress a thought, to actively take it away from their mind, the thought tends to grow more persistent and intrusive. Researchers call this ironic process theory. People who try to stop thinking about something experience that thought more frequently than people who simply let themselves think about it. The mental “hole” you’re trying to create by removing a thought only gets bigger with effort.
So the next time someone asks you this riddle, you have the answer: a hole. And if you want to sound clever about it, you can point out that lungs, wounds, loose skin, and even your own thoughts all follow the same strange rule.
