Actually, I'm not sure what the real origin of this is, I just know in Portugal the balloons are used for the São João Festival. As a kid in the 70s in Sweden, my sister and her boyfriend made the same type of balloon from scratch. It was a days work to cut and glue the different parts of the balloon together, and when the evening came, the entire family went outside to fill the balloon with hot air with the help of a torch or hot air gun. Quite often, it ended up in a dramatic fire. This balloon comes with a candle that, when burning creates hot air, which fills the balloon, so it takes off. Up, up and away! Nice gift. Best at dusk in an open space. No wind please. Follow manufacturers instructions and use at your own risk! Instructions and video this way!
