Glow necklaces, although they've been around for some time, have become the latest craze in rave and holiday fashion. Coming in a variety of colours, glow necklaces have become especially popular with children as well as adults. With their roots deeply ingrained in rave culture, the items have become increasingly popular in all walks of life, to the point where many people now hold glow necklace parties and utilise the accessories for activities such as night-time golf.

Essentially, glow necklaces work around a chemical reaction which takes place when its two constituent chemicals are mixed together. The colourful light effect which ensues will last for up to twelve hours. The chemical reaction is initiated by bending and cracking the necklace, causing the chemicals to mix and emit their glowing effect. Glow necklaces can't be switched off, but you can prolong their life by putting them in the freezer, causing the chemical reaction to slow down and the luminescence to last longer. Your glow necklace will glow a lot brighter when exposed to heat, but it will not last as long as it will at lower temperatures.

Due to the versatility of the chemicals used, the accessories are available in both single and multi-colour styles, including pink, green, blue, yellow and more. The vast majority of glow necklaces are non-toxic, too, meaning that they are completely safe for children and adults alike. The chemical liquid, cunningly named 'glow juice' is remarkably similar to the one used in school chemistry experiments, whereby two clear liquids are mixed to create a coloured liquid. Self-activated necklaces contain one of the chemicals inside a thin glass ampule, with the second chemical surrounding the ampule. When you bend the liquid, the glass cracks and the two liquids mix. Shaking the glow necklace will help with the mixing effect.

Glow necklaces work fantastically at laser shows, concerts and any other type of party or celebration where the ambient light will be dark. In fact, this is exactly where glow necklaces first originated, with their roots in rave culture. Originating in Europe, Canada and America, rave parties became infamous and notorious due to alcohol and drug consumption and an air of carefree hedonism. Young ravers often wear bright and gaudy clothing and glow necklaces go perfectly with this kind of attire. Of course, the culture has since changed and glow sticks and necklaces are now available in all walks of life, being most common with children at firework parties and other celebratory events.

Many people have been known to hold every increasingly popular glow stick parties, whereby all guests will be donned with glow necklaces and bracelets during a party which largely takes place in the dark with the glow sticks giving off the light. These parties have proven to be extremely popular and have emerged at a time of 'niche' parties such as foam parties and silent discos. As glow sticks have been around for many years and have long passed the stage of being simply a fad, you can be sure that they are a fashionable accessory and that your glow necklaces will be the centre of attention at any party or function. With such a large range of different products available and all based around the same science and technology, glow sticks make for a fun and versatile accessory with many different uses.
