Easy but fun practice in which the teacher shows heat convection using a tea bag from which the teacher cuts both ends in order to empty it, then makes a cylinder with it and places it on top of a paper (or a 5 euro note) and burns it from the top. Is this magic? not, thanks to convection currents (hot goes up and cold goes down) the tea bag flies up and away from the paper (or bank note).

La bolsa de té
Práctica sencilla que muestra la convección del calor, en la cual el profesor corta los extremos de una bolsa de té para así vaciarla de su contenido, tras lo cual la coloca en forma de cilindro sobre un papel (o billete de 5 euros para los que quieran hacer el truco estas navidades a algún familiar que se los quiera apostar :-) y se le prende fuego por arriba... ¿magia? no, gracias a las corrientes de convección (caliente sube, frío baja) la bolsita sube antes de prender el papel (o billete) sobre el que está colocada.
Prendiendo fuego a la bolsa de té.
