OBJECT MADE OF PAPER FOR DECORATION PURPOSE
Party streamer
A serpentine streamer is a type of party accessory made out of long strips of paper, wound up in a roll. When thrown up in the air they create beautiful serpentines, and their motion through air is fun and aids in party cheerfulness.

Spark chamber

A spark chamber is a particle detector: a device used in particle physics for detecting electrically charged particles. They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and silicon detectors. Today, working spark chambers are mostly found in science museums and educational organisations, where they are used to demonstrate aspects of particle physics and astrophysics.

Spark chambers consist of a stack of metal plates placed in a sealed box filled with a gas such as helium, neon or a mixture of the two. When a charged particle from a cosmic ray travels through the box, it ionises the gas between the plates. Ordinarily this ionisation would remain invisible. However, if a high enough voltage can be applied between each adjacent pair of plates before that ionisation disappears, then sparks can be made to form along the trajectory taken by the ray, and the cosmic ray in effect becomes visible as a line of sparks. In order to control when this voltage is applied, a separate detector (often containing a pair of scintillators placed above and below the box) is needed. When this trigger senses that a cosmic ray has just passed, it fires a fast switch to connect the high voltage to the plates. The high voltage cannot be connected to the plates permanently, as this would lead to arc formation and continuous discharging.

As research devices, spark chamber detectors have lower resolution than bubble chamber detectors. However they can be made highly selective with the help of auxiliary detectors, making them useful in searching for very rare events.
