20pcs Tactical Glow Stick Set - Mix of Colors - A glow stick is a single-use light source that does not require an electrical power source. It is build from plastic tube containing isolated substances that, when combined, make light through chemiluminescence. Glow sticks are often used by military, police, fire brigade and also by civilians. Light sticks give off light when two solutions are allowed to mix. The sticks consist of a small fragile container within a flexible outer container. Each container holds one of the two solutions. When the outer container is bent, it breaks the inner container, releasing the first solution into the second solution. After breaking, the tube is shaken to mix the two components. Average lighting time is 9 hours. NOTE! The set includes 20 pieces (5 colors, 4 pcs: blue, green, yellow, orange, red).
