Watch age restricted youtube videos without login

Some time You tube video uploader add age restriction to their videos, like EA have done (as i found)on most of their game trailers videos, so you have to login to your google account to prove that you are 18 or above. But some of us dont want to do login because  it get stored in our google history or because some does not meet the age requirement ,so i found a way (probably you may also know so dont spam )to watch age restricted videos on you tube without login so i am going to share a trick to bypass age restriction on youtube .

STEP 1: As for example i am going to bypass login for this video :https://www.youtube.com/watch?v=1VCA17t0rts

STEP2: Now you have to just remove  watch? and replace = with  /

so the link is (Battlefield hardline single player trailer):

https://www.youtube.com/watch?v=1VCA17t0rts

We will change similar to this  :

https://www.youtube.com/v/1VCA17t0rts 

So now you will see video will start loading in full screen mode as shown below

And yes i am not going to tell about adding "nsw" before you tube on the URL because that will redirect you to another site !!
