    Glow sticks glow when you crack/bend the stick. When you crack it, it is releasing energy in the form of light what makes the glow stick glow. Inside the glow stick, there are two chemicals, when you crack the glow stick the two chemicals mix, causing a chemical reaction between the two, the liquid inside the glow stick will then change from a white liquid into a coloured liquid and this is because of the chemical’s mixing which is what causes the glow effect inside the glow stick.

    Glow sticks glow when two chemicals mix together causing a glowing reaction they are white when they are separate but are coloured when they mix these colour’s are red/pink,blue and green. When your snap the glow stick it is actually the two chemicals mixing.There are two tubes in a glow stick each one holds a different chemical but all glow sticks have the two chemicals for the same reaction. Glow sticks are not powered by batteries and it is not magic, it is just chemical reactions.

    glow-sticks are formed from a chemical reaction. That chemical reaction is 2 chemicals getting mixed together this is called chemaloomanescence. When those two chemicals get mixed together it forms that glow that you see. It turns out that the cracking sound that you hear is actually two little things that hold the chemicals breaking, releasing the two chemicals to mix and form that glow. So it turns out that glow-sticks aren’t battery powered it is just pure science

    Glow sticks may be a toy but they are actually full of chemicals! When you break a glow stick it will release energy in the form of light. The cracking sound you hear is the two ampules breaking into each other. Once the chemicals have mixed they then begin to glow.

    Glow sticks glow without a battery. This happens by two specific chemicals inside the glow stick. The two chemicals mixing create the glow that you see when you snap a glow-stick. If you dissect a glow-stick (pull it apart) you will find two tubes. These tubes contain one of the two chemicals in each. This is how glow-sticks work.

    A glow stick isn’t powered by batteries. It’s powered by chemicals. It’s when you crack up a glow stick, the chemicals have an reaction. Chemical reactions can change colour, sometimes it gets bubbly and gets hot. But a glow stick is nice and cool. A glow stick releases energy from a form of light. The secret is that there is two chemicals in a glow stick. When you crack the glow stick, those two chemicals combine which causes the glow stick to form light.

    Glow sticks glow when two chemicals have a reaction when you mix them. inside a glow stick there are two tube each tube has a different chemical. When you snap or bend a glow stick you hear a crack. This is the tubes breaking. soon after you hear the crack it starts to glow because it is letting out energy in the form of light. You can make a new colour by mixing colours. So believe it or not glow sticks do not use batterys.

    Glow sticks are made out of to chemicals that mix together to make it glow. So when you snap the glow stick that’s just the chemicals snapping into a liquid that can be mixed into different colours.
    When this happens it forms into a glow stick without using any battery’s.

    Some people think glow sticks work off a battery, this is a myth. The Glow comes from two chemicals mixing together to make a chemical reaction. In the glow stick there are two tubes, they have different chemicals within. When you “snap” the glow stick your not snapping the actual glow stick, your snapping the tubes inside of the stick. In the dark the stick glows. Thats how a Glow stick works.

    How do glow sticks work?
    There is two specific chemicals mixed together to make the liquid glow, that’s when a chemical reaction happens. Most chemical reactions have something happen like it might change colour, there might be bubbles or there might be heat but these are cool it’s called chemiluminescence which means it’s releasing energy in the form of light. when the chemicals are joined it is a white liquid but when they are separated they either have a colour of Red, blue or green.
    And they glow with no batteries!

    GLOW STICKS.Some people think that glow sticks are powered, but it’s not. The liquid in the stick reacts with the chemicals, so that means it will form some sort of bubbles,heat and of course it would Glow.The effect of glowing is, when the liquid mixes with chemicals, it will turn (slowly) into glow.Did you know, when you crack the glow stick the chemicals will meet and form a reaction.Did you also know, the actual glow stick is heated, but on
    the outside it is cool and its called chemiluminescence.

    Some people think that glow sticks are battery powered, when they are not. When a glow stick is cracked, it releases two chemicals. One chemical is coloured and the other one makes it glow. If you pull glow sticks apart, you will find that there is a tube inside. This has the coloured chemical inside and the other chemical is just floating around in there. This is how a glow sitck is formed.

    Glow sticks glow without a battery
    How?
    A chemical reaction that happens sometimes the colour changes, it bubbles or heat.
    Chemiluminescence releases energy in the form of light and this is in the glow sticks so they glow when it gets broken.

    Glow Sticks,
    Glow sticks glow because there is 2 chemicals inside that when you break the glow stick the 2 chemicals mix together to make a glowing effect. This is called chemiluminescence. When you pull the glow stick in half then you will find the 2 chemicals inside.

    The glow is formed by a chemical reaction. When you snap the glow stick two chemicals react to that, forming the glow. One chemical makes the colour another makes the glow. Some people think the glow stick is battery powered, but it is not.

    When you snap a glow stick in half and shake it, it will glow. This is a chemical reaction which is called chemiluminescence. Therefore, they are not battery powered. Glow sticks have two chemicals inside. When they crack or are mixed, they come together and form the light or glow.

    Some people think that glow sticks work with a tiny power battery inside it, but NO.
    A glow stick works WITHOUT a power battery by it having a chemicals inside of it, the chemical is forced to light up when two ampules snap together, these ampules are to contain the chemicals to make sure that the chemicals don’t burst up. Both chemicals inside it are different colours but it is working by, chemiluminessance is what helps the chemicals to work…

    That Is How A Glow Stick Works( ͡° ͜ʖ ͡° )( ͡° ͜ʖ ͡°)

    How Do Glow Sticks Work?

    Did you know that glow sticks work without a battery. They are formed by a chemical called
    Chemiluminescence which releases energy. So when you break it it changes colour.

    Well people think that glow sticks run with a small battery but they
    DON’T it has chemical called chemiluminescence inside of the glow stick and and when the chemicals touched the two ampules snap together and it makes a colour.

    Glow sticks glow when two chemicals are combine to make it glow. When you have a glow stick in the middle it has two chemicals to make it crackle. Some people think that the glow stick runs on a battery but it is actually two chemicals con bind.
