    The Bar clips are different. In the first clip you can see he is not passing his teeth over his lips in the second clip you can see his teeth passing over his lips indicating he is making the FR sound.

    If you look at his teeth the first time it isn't touching his lips then the second time he is so you can just tell he's saying two different words

    Lads look at when he compares the first two sounds bar and far , he says they are the same clip but how come the right face puts his bottom lip back to pronounce an f and the left guy doesn’t is it just me ?!?!?!

    The climbing tone part was weird for me. It was like the opposite. Where the second one ended the first one started, so weird

    Watch his lips in the beginning

  • LegendDragon04 // PilotPikachu

    Actually on Bar and Far
    His lips curled inwards into the mouth meaning he made the f sound. On bar he didn’t do that. The problem isn’t my hearing, but the movement of the lips according to your speech.

    (I did not look further into the video) You heard far because your brain sees lip movement and sees "OH HES SAYING FAR! HAH EARS!" But if you remove the video, you hear bar

    In the first video of far and bar, they are diffrent to me. When the show the video side by side, on the left side, his lips are going on the backside of his teeth which makes an f sound, on the other one his lips don't go behind.
    This is just what it looks like to me🤗

    0:23 THEORY:
    Notice how Greg's mouth is moving differently; it's how your mouth moves when you say an 'F' sound. So your brain takes that in and concludes that Greg is saying 'Far'.

    EXCELLENT video!!! I’ve been a huge fan of the BLR videos ever since I discovered them and cannot get enough of them. So of course, I decided to try and make one myself since, obviously, it couldn’t be that hard…. WRONG! Yes, those videos are hilarious, and after watching this video and learning about the science behind why they seem so spot-on, I’m an even bigger fan of not only the videos but how amazing/weird our brains really are. Thanks for posting this!!!
