You might think that plastic box filled with sand and attached to a string is just that, a plastic box filled with sand attached to a string. Little do you know, it's really a barco, or boat. This is the hot toy in Gigante right now. Another variation is made from discarded motor oil bottles. The kids run around and drag their barcos behind them. What you have to watch out for is when they stop and swing the things around at about 90 miles an hour. You don't want to catch a barco in the cabeza.
