Brain teaser: Can you guess which bucket will fill first?

Optical illusions and puzzles are almost the same as they both trick our minds in such a manner leaving us perplexed with the answer or an explanation. They confuse our eyes and squeeze our brains. It is how an optical illusion works, but amongst all one such optical puzzle is now making rounds online with people guessing the answer wrong, but you can prove them wrong and can stand out from the 90% crowd.
In this image, you will be able to see a row of buckets filled with water. Amongst these buckets, water falls into the first numbered bucket, but there is a way via which the water will go to the other buckets as well. Thus, your task is to find out which bucket gets filled first and then go ahead and pour water into this bucket. Run your mind fast and move ahead with the answer.
But, remember that these types of optical puzzles usually require your full attention of eyes and mind, but at the same time, it also requires the attention of cognitive strength. It requires your logical and reasoning skills as well, where you need to think in a sharper manner giving your thinking skills a chance to go one step ahead from your strong eye game. But, keep in mind that your time is tickling.



Do not worry as the time is up but we have your answer. There are a total of 7 buckets, thus when water is poured into the first bucket, it flows into the 3rd bucket. The pipe from the 3rd goes to the 4th which is closed. Now, the pipe leading to the 5th is also closed, and similarly, the 2nd and 6th bucket is also closed. The water in the 2nd is lower than the 6th, therefore, the water falls into this first bucket which is the 3rd bucket, and after that, the 7th bucket will get filled first.
