Great videos. Thanks for posting.
On Don Antonio's you can see that you really do not need too many tools to make a top (but it is nice to have them, of course).
I have a guess for what the rules of the game played at the end of the second video might be. There is a target top that it is used as a "ball." The street has chalk marks indicating distances from the starting line. So I guess you get points for how far away the target top ends. They first try to hit it with the string throw. If they succeed and their top is still spinning, they can scoop it and throw it with the hand to try to push it further away. They can repeat this as long as their top continues to spin, what they call "trompo vivo" (spintop alive). For the final "throw-down" to decide the champion, one player tries to push it in one direction, the other player in the opposite direction, and a the end of a fixed time they see on which side of the line it ends.
I know that in Chile, Ecuador and Venezuela they also have games in which they push the target (not necessarily a spintop) by hitting it with a top that they have previously scooped into the hand. I would need to practice my big scoop before going over there . . .
