Glow bracelets are just one of the many glow products you can now buy. Originally glow items were restricted to glow sticks themselves – the original and still popular trendsetter – and a couple of other items like glowing necklaces and wands.
These were waved at after-dark events such as music concerts and gave rise to the term 'glowsticking'. If you want to explore regarding chemiluminescence detection tool then you can search the browser.
(In some cases, glow sticks are attached to strings so that they can be swung around the body in shapes, from the basic figure-of-eight to more complicated designs – much in the same way that you can 'write' in the air with a sparkler.)
All of this heralded a move towards using glow stick wands, necklaces and other items like glow bracelets increasingly as a form of body art and personal expression. Now, sites cater for virtually every glow desire imaginable, and there is a whole culture built around glowsticking.
The glow bracelets work just the same way that regular glow sticks do: snap the little glass vial inside and shake them, and the contents inside will mix and produce the chemical reaction that releases the characteristic glow (chemiluminescence is the technical term).
You can buy different colors of a bracelet, which are filled with different dyes that react differently to the energy released from the reaction.
Glow bracelets are typically very cheap – you can buy them for far less than a glow stick or a necklace. From a good site and at bulk prices, you can buy six-inch glow sticks for 1 a time (or 1.50 for huge 'concert-grade' sticks), 30p for a necklace and just 10p for a glow stick bracelet.
This means that they are a really cheap accessory to add to your other glow in the dark paraphernalia.
