YouTube published a list of the top 10 most watched 2018 Soccer World Cup videos. As you would expect most were highlights of matches played. In top spot is the highlights of the 3-all game between Spain and Portugal in the group stage with close to 56 million views.
But number 6 on the list was something quite different. Three guys decided to find out just whats inside an official World Cup soccer ball...
They got one from 1930, which was the year of the very first tournament in Uruguay, one from 1970 and one from 2018. It received around 18 million views.
Watch them cut open the balls and see what is inside! Hint: The 2018 version has a tracking chip buried in the ball.
