Sky lanterns have been made for centuries in cultures around the world, to be launched for play or as part of long-established festivities. The name sky lantern is a translation of the Chinese name but they have also been referred to as sky candles or fire balloons.
The key to understanding the behavior of the balloons is understanding how the pressure inside a balloon varies with the balloon's diameter. The simplest way to do this is to imagine that the balloon is made up of a large number of small rubber patches, and to analyze how the size of a patch is affected by the force acting on it.
Balloon skewer experiment. A pin or needle is frequently used to pop a balloon. [4] As the needle or pin creates a hole on the balloon surface, the balloon pops. However, if tape is placed on the part where the hole is created, the balloon will not pop since the tape helps reinforce the elastic tension in that area, preventing the edges of the hole pulling away from the center.

Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.

The antiphon's text, whether the Latin original or a vernacular translation, is sung to traditional hymn tunes. The blessing of palms and the intonation of the antiphon often occurs in the church's parvise, its parking lot, or the town plaza, which usually is in front of or near the church (a common layout in most Philippine settlements).
