Una de las costumbres más antiguas y extendidas por el mundo para celebrar el aniversario del nacimiento de una persona es con una tarta de cumpleaños, a la cual se le colocan velas, para que el cumpleañero sople y las apague mientras los invitados cantan alguna canción de cumpleaños. Más recientemente y especialmente para los niños, se han sustituido las velas por fuente de fuegos artificiales dado que resultan más espectaculares. No obstante, la quema de fuente de fuegos artificiales convencionales no es recomendable efectuarla sobre productos alimenticios tales como tartas de cumpleaños porque provoca desechos de papel y cenizas que caen sobre la superficie de la tarta, además de humos y olores, por lo que tiene implicaciones indeseables para la salud además de dejar un residuo desagradable. One of the oldest and most widespread customs in the world to celebrate the anniversary of a person's birth is with a birthday cake, on which candles are placed, so that the birthday boy can blow out and blow them out while the guests sing a song of birthday. More recently and especially for children, candles have been replaced by a source of fireworks since they are more spectacular. However, burning conventional fireworks fountains is not advisable on food products such as birthday cakes because it causes paper waste and ashes to fall on the surface of the cake, as well as smoke and odors, so it has implications. undesirable for health in addition to leaving an unpleasant residue.
Por otro lado, el proceso tradicional de construcción de una fuente de fuegos artificiales es llenando un tubo con una composición pirotécnica para que al quemarse forme una fuente chispeante, pero el proceso de fabricación de este tipo de artilugios es enormemente dificultoso puesto que no se puede emplear maquinaria y se debe realizar de forma manual. On the other hand, the traditional process of constructing a fireworks fountain is filling a tube with a pyrotechnic composition so that when it burns it forms a sparkling fountain, but the manufacturing process of this type of device is enormously difficult since it cannot be use machinery and must be done manually.
