Yes, a glow stick can be considered a smart material due to its ability to chemically produce light without the need for an external power source. The chemical reaction inside the glow stick, which involves oxidation of a dye by a peroxide, allows it to emit light for a certain duration.

What is the name of the substance that makes a glow stick glow?
The substance that makes a glow stick glow is called a chemical dye or phosphor. This substance is contained within the plastic tube of the glow stick and reacts with other chemicals inside the stick to produce the glowing effect when activated.
Is breaking a glow stick a chemical or physical change?
It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.
Is a glow stick endothermic or exothermic?
A glow stick reaction is exothermic, meaning it releases energy in the form of light. This is because the chemical reaction inside the glow stick produces light as a byproduct of the reaction.
What chemicals make a glow stick glow longer?
To make a glow stick glow longer, you can use chemicals that slow down the rate of the chemical reaction that produces the light. One way to do this is by using a higher concentration of hydrogen peroxide or a lower concentration of the dye in the glow stick solution. This can help make the glow stick last longer before the reaction is fully used up.
How much liquid is in a glow stick?
A glow stick typically contains a combination of hydrogen peroxide, a fluorescent dye, and a solvent (usually dibutyl phthalate). The total volume of liquids in a glow stick is usually around 4-10 milliliters, but this can vary based on the size of the glow stick.
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.
Who created glow stick?
The person who invented the glow stick is Thomas Edison

What do you do with the glow stick on poptropica?
you get the glow stick in the left hand side of the corner in the tunnel
Wheres the glow stick in early poptropica?
the glow stick is in the well ☺♥
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.
Which dark cave is the glow stick in on Early Poptropica?
The dark cave is not where the glow stick is, but rather where it is needed. The glow stick is down in the well in Early Poptropica village.
Is a glow stick endothermic or exothermic?
A glow stick reaction is exothermic, meaning it releases energy in the form of light. This is because the chemical reaction inside the glow stick produces light as a byproduct of the reaction.
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.
What do you do after you find the glow stick?
After you find the glow stick find the golden egg that belongs to the giant.
