Only Special People Know Which Cup Fills First

There are times in life when we get a chance to test our minds, and it’s good to seize those opportunities. Challenging yourself not only helps to reaffirm your intelligence, but it can also make you sharper.

Below, we have an intriguing puzzle that has been stirring up quite a debate online. The task is simple: as liquid is poured into the top, you need to figure out which of the cups at the bottom will fill up first.

This puzzle will require some careful thought. While some may be quick to guess, others might take a bit longer to reason through it completely.

There are several factors to consider in this image, and it’s not immediately obvious which cup will fill first. Remember, there is a logical answer, and your task is to determine it.

After you’ve had a moment to ponder, do you have your answer ready? I’ll reveal the solution below, but make sure you have your guess before you read on.

To solve this puzzle, note that the paths to cups 7, 5, 4, and 3 are blocked, so they will never fill. The only open cups are 1 and 6.

As the liquid flows into the pipes, it travels straight down and hits the elbow joint positioned above cup number 4. Once the tube fills, the liquid spills out and travels downward to fill cup number 6.

So, the correct answer is cup number 6.
