You might think what's the big deal about that, you can just search the title on the YouTube and problem solved. Well, although you can search the title and find it out but it might take some time, and sometimes you might get carried away with other videos and end up finding nothing at all.
In this post I will try to show you how you can find exact same video that you want to watch.
If you are watching the video on mobile then you need to find out the link first. If you don't know how to do that then read this post which shows you how to get the link in detail.
You will find the 11 characters video ID like this NEKMdUS3G0s it includes capital letters lower class plus numbers, be careful copy ever single character as how it is.
Sometimes you might get mixed up with capital letter "I" with lower class "l" so if that happens just swap the the letter.
After getting the video Id just search on YouTube and it will bring the exact same video that you were watching.
