So the story here is that a young boy got lost and separated from his mother on a beach in Brazil.
Apparently Brazil has a technique that's very popular because this happens all the time.
They start clapping in unison until the parents realize they pretty much lost a kid and find him or her.
The child is usually placed on the shoulders of the tallest person around as well to be easily spotted.
Overall, pretty genius!
The mother & child reunite at 0:45 seconds.
