Do you think this is real? I need to know

Someone recently sent me an email with this link. Since I am a curious person I clicked on the link. Then I spent the next two minutes watching various groups of people pop popcorn with their cell phones. It freaked me a bit. But then I got suspicious because there is one video and it seems to show people from different parts of the world all trying the same experiment and getting the same results. How did someone really find people from different parts of the world to participate in his or her video? Seems like a lot of effort (and therefore, it seems to me like unlikely effort). So I am hoping that some of you will watch it and tell me what you think.
