What happens when you snap a glow stick to make it glow?
When you snap a glow stick, a glass vial containing hydrogen peroxide inside the stick breaks, allowing it to mix with a solution containing phenyl oxalate ester and fluorescent dye. This chemical reaction produces light, causing the glow stick to illuminate in the dark.
What happens when you break a glow stick?
When you break a glow stick, a glass vial inside the stick containing hydrogen peroxide is broken, mixing with a solution containing a fluorescent dye. This causes a chemical reaction that produces light through a process called chemiluminescence, making the glow stick glow.
How long does a glow stick glow?
Glow sticks can last over 4 days if you get the right ones. It usually depends on the colour and size of your glow stick. To make the glow stick last longer throw it in the fridge freezer to slow the chemical reaction down.
What happens if you take 2 styrofoam cups and fill one with cold water and one with hot water and drop a glow stick in each?
The glow stick in the cold water will glow dimmer and last longer because the chemical reaction is slower at lower temperatures. The glow stick in hot water will glow brighter but will also burn out faster due to the increased speed of the chemical reaction in the warmer environment.
How long can a glow stick glow?
A typical glow stick can glow for around 6-12 hours, depending on the size and quality of the glow stick. After this time, the chemical reaction that produces the light gradually diminishes and the glow fades away.
