What makes glow sticks glow longer

This article has been viewed , times. Learn more Glow sticks have a short lifespan, and there's only one way to extend it. This works better for some brands of glow sticks than others, and not at all if you're unlucky. Still, it's easy to do, and you can learn how glow sticks work as you try it.

To make glow sticks glow again, try freezing them to extend the glow. First, crack the entire length of the glow stick to try and find some light. If the glow stick lights up, even in just one spot, this means you might be able to make it glow again. Then, place the glow stick into a plastic bag, as this will contain any mess if it accidentally breaks. Store the glow stick in the freezer for 1 hour, before removing and checking it. Shake the glow stick and crack it to see if it starts glowing again.

If no light at all appears, your glow stick is completely used up and there's no hope for it. If you can get a tiny bit of light, even just a couple spots, you've got something to work with. The light in a glow stick is caused by a reaction between two chemicals.

One is kept inside a glass tube. Cracking the tube breaks the glass and lets the chemicals mix and react. Cracking too hard will break the glow stick and spill glass and goo that can irritate the skin. Seal the glow stick in a plastic bag. Put the stick in a zip-locked bag. Then when it gets dark, run the tap on warm and hold the glow stick under the water to warm it up until it starts glowing again.

Some glow sticks can last a few nights by storing them in the freezer during daylight hours. However, do not thaw frozen glow sticks in the microwave, as they do contain hazardous chemicals. For a really long-lasting glow, choose a green or yellow glow stick. The fluorescent dyes used in these glow sticks tend to have the most staying power. Blue and purple glow sticks will also glow brightly, but they will not last as long as the chemical reaction takes place more quickly.

Purple, in particular, will have a shorter lifespan. If you need a glow stick to last for a long time, choose a bigger one. The chemical reaction will continue longer because there are more chemicals contained in large glow sticks to react. The larger the glow stick is, the longer it will glow. Glowsticks are affected by temperature. The chemical reaction inside a glowstick is sensitive to heat and extreme cold. The speed of the chemical reaction speeds up considerably in high temperatures causing the glowstick to glow brighter but for a shorter period of time.

Exposure to extreme cold and freezing conditions dramatically slows down the chemical reaction resulting in a duller glow that lasts much longer than usual, so if you want to prolong the life of your glowstick, pop it in the freezer!

Glowsticks are available in more than just one shape. The standard six inch glowstick is the most recognised shape, but the same concept has been applied to make glow necklaces , glow bracelets , glow cups and even glow in the dark bunny ears!

These colours are the purest and therefore the brightest as they contain less fluorescent dye than other colours. A glowstick cannot be turned off or reused once activated. Once you start the chemical reaction it can only be slowed be placing in extreme cold but will not stop entirely. A glowstick will glow until the chemical reaction is complete. Glowsticks are a safe light source. Glowsticks use non toxic chemicals and are non flammable. Glowsticks have endless uses and are popular for use in all walks of life.
