History of Glow Sticks

Glow stick is a self-contained instant light source. It consists of translucent plastic tubing that emits light when coupled together. It does not require additional external energy. It was impossible to turn off the light after the "thin", but the light stick can be used again in fact, it is said to break again after putting it in the refrigerator overnight. Since the light emitting stick is easy to carry and easy to launch, it is used in many ways for emergency settings, entertainment, entertainment and military use.

Procedure: First, put the glow stick in water at 20 degrees Celsius, the glow stick is kept at 4 lumens. Then take another glow stick (the same brand), crack the control variable glow stick and glow stick at the same time, and place it underwater at 20 degrees Celsius and leave only the control variable as it is. Water temperature is the manipulated variable. The amount of lumen is the response variable. Ice was then added to the beaker until the temperature dropped to 5 ° C. and the brightness was recorded in the lumens. Then remove some ice until 5 degrees higher (10 ° C) and continue doing it to 35 ° C, since it will no longer work at 37 ° C.

Tel Aviv in Israel: Chemiluminescence or chemiluminescence is the principle behind glow sticks (also called glow sticks) used in rock concerts and is a quick way when current dies out. However, they can also be used to diagnose disease by specifying the concentration of the biological sample. A new mechanism developed for researchers at the University of Tel Aviv (TAU) to generate waterproof chemiluminescent probes of 3000 times the brightness, especially for medical and cancer diagnostics

A marine organism such as a squid radiates light by mixing two substances to one-third of the light, just like a normal firefly light mechanism and a popular plastic green sparkle works To do. To make the glow stick "glow" it will bend. This causes the two internal chemicals to intermix and react to produce the third luminescent material. The same thing happens basically also in certain luminescent cells (photocells) or organs (photonic cells) in vivo. A substance called fluorescein reacts with oxygen in the presence of the enzyme luciferase. When the reaction is complete new molecules are formed, which usually emit a blue to green color at the sea. In some organisms, photobio is a simple gland cup. In other cases, they are sophisticated devices with adjustable flip for use as a focusing lens, color filter or off / off switch.
