Here’s a classic brain teaser: What can you hold in your left hand but never in your right hand?
The answer: Your right elbow
You can use your left hand to reach across your body and hold your right elbow. However, your right hand cannot ordinarily grasp its own elbow because it’s attached to the same arm.
Why the question fools us
Many people start by looking for an object that can only be held with one particular hand. The trick is that the answer isn’t an ordinary object at all: it’s part of your own body.
This is a fun example of a riddle that depends on how the question is worded rather than complex facts or calculations.
Try it yourself
First, hold your right elbow with your left hand. Then try to repeat the movement using your right hand. That simple test shows why the answer works. Did you figure it out before trying it?
