AS somewhat of an authority on all things related to glow, www.glowsticks.co.uk are often posed with the question, ‘How do glowsticks glow?’ and so to answer this question, Glowsticks.co.uk have put together a handy infographic style guide to explain the process in an easy to understand, informative way.
Much like glowsticks themselves the infographic is bright and colourful with clear information to explain the process and makes a fantastic teaching aid.
How do glowsticks glow? explains the secrets of a glowstick with clear illustrations that break down the chemicals into colourful characters that come together to release light in a process known as chemiluminescence. The guide explains how Hydrogen Peroxide, the very chemical that’s often used to bleach hair is contained in a very fine glass tube that floats within a mixture of tert-butyl Alcohol (a colourless liquid that’s soluble in water and often used in perfumes and food flavourings), and fluorescent dyes that are used to colour the glowstick.
The fluorescent dye gives colour to the glowstick and green, yellow and orange glowsticks typically glow the brightest of all as they use less dye in their composition.
The colourful guide then goes on to give a step by step guide to what happens when you bend, snap and then shake a glowstick. The bend and snap motion breaks the glass tube and allows the chemicals to mix causing a chemical reaction to take place and by shaking a glowstick you’re simply helping the chemicals to mix that bit faster leading to a brighter glow from the start. When the two chemicals meet, the electrons in a glowstick become excited and create a bright glow as a side effect of the reaction known as chemiluminescence. This bright light without heat is what makes a glowstick glow and the colour of the fluorescent dye (not the colour of the plastic outer tube) determines the colour of your glowstick.
A typical good quality glowstick will glow brightly for up to twelve hours, this being the length of time that the electrons remain excited and as the electrons calm down and return to their normal levels they gradually release less energy making the glowstick dim. The chemical reaction will usually be complete within a 24-hour period.
A helpful ‘go to’ guide, How do glowsticks glow? Is clear, concise and fun but more importantly explains the process of chemiluminescence with fabulous illustrations that the reader will easily recall time and again.
