After watching the video, explain how glow sticks work without a battery.

  1. you can make glow sticks work without a battery by mixing certain chemicals that will make a chemical reaction and then it will start to glow but it depends on which types of chemicals you use to make a certain type of color. So if you mix the two chemicals together to make them glow you can’t make them turn the color you want by hoping it will happen. No matter how many times you mix the same chemicals to make them glow the color will never change. so you have to mix the right chemicals to make a glowing liquid and the color you want.

  2. Glow sticks work without a battery because inside a glow stick there are two chemicals. When you crack glow sticks the two chemicals mix which causes a chemical reaction and cause the glow stick to glow. The chemicals inside a glow stick are energy in the form of light.

  3. ~Glow-sticks work without batteries because there are two chemicals inside the glow-stick itself which make the glowing part of this the glow-stick.
    ~ The reason the glow-stick makes a cracking sound is because both of the chemicals have been put together and it makes the cracking sound.
    ~ The two chemicals in the glow-stick is, one being a part inside the bit that makes it glow, and two, a part in the the container that holds everything together.

  4. I was shocked when I found out that glow sticks don’t have any electricity, I did know that glow stick are a liquid but I thought it did have electricity.

    I wonder how they make the glowing liquid for the glow sticks? And HOW does it glow by itself?

    I think that this liquid is not dangerous but if you drink it might poison you.

  5. Glow Sticks work without a battery because inside the little plastic container thingy, there are two chemicals.
    When you hear that CRACK noise, that is the sound of the two chemicals mixing together and forms “chemiluminescence” witch means it releases energy by a chemical reaction .

  6. Glow sticks work without a battery because of a chemical reaction, that is why they don’t require batteries. 🙂

  7. Glowsticks

    Glowsticks are made of a chemical reaction which make the liquid glow.
    There are two liquids in a Glowstick which combines when you shack it. When the liquid combines it glows because of the chemical reaction.
    When they are combined it is called chemiluminescence.

  8. Many kids think that glow sticks work because a battery is making it glow . This is not true. Glow sticks work by two chemicals mixing together to make a reaction called chemiluminescence. If you look at the word you can see the word luminous (meaning glowing or bright) , and the word chem (being a short way to say chemical). There a two tubes inside the glow stick. Each of them have a different chemical that when released, they mix to make the glow stick glow. The snap that you hear when you crack a glow stick is the two tubes breaking, therefore releasing the chemical to make it glow.
    That is how glow sticks work

  9. Glow sticks

    Glow Sticks have chemicals that help them glow. They can be mixed together and still glow. Most people think they have batterys but they don’t this is caused by the two chemicals this is a unusual reaction but it is still really cool.

  10. Glow sticks are able to glow because of a chemical reaction called chemiluminescence, this means the energy is released in the form of light. This also means that glow sticks can glow without batteries.

  11. Well done An Quan.

  12. Most children think that glow sticks are battery powered, (like what I thought) but their not. When we snap it, that is the sound of the 2 chemicals mixing, called a chemical reaction. This chemical reaction in this case is glowing. That’s why glow sticks are called glow sticks.

  13. Glow sticks work without using any battery by having two different chemicals mixed together. These two different chemicals and like in tubes with the chemicals inside them. So when you go to crack them this is what brakes and makes your glow stick glow. This is why when sometimes you crack them multiple times they start to leak and the chemicals inside it goes everywhere.

  14. ~Glowsticks~
    Glowsticks have 2 chemicals in them, when you bend and crack a glow stick the two chemicals mix together, causing a chemical reaction which makes the stick glow. The CRACK sound in a glowstick is made by the 2 chemicals connecting and mixing together.

  15. Glow sticks work without a battery because there is two chemicals inside mixing together, which causes a chemical reaction when you snap the glow stick.That causes the glow stick to glow.
    Even if you take the chemicals out of the tube, the chemicals can still glow.
    So that’s why glow sticks can work without a battery.

  16. The glow sticks glow because of a chemical reaction, when you bend, crack, and then shake. This causes the chemical to glow without electricity.

    I didn’t know entirely how glow sticks glow until now when I watched the video.

    I was pretty shocked when they spilt the liquid and wiped the cloth with it and it was still glowing!

  17. Glow sticks work with out a battery by two chemicals that mix together to make a bright glowing object that people can play with.
    Glow stick are a tube that when you crack it turns into a chemical that is cool to touch with your hands.
    Some glowing chemicals are very hot that glow but you can not touch so the glow stick I a good object that dose not use a very hot chemical that people cant touch, this is why people can hold it and play with it.

  18. The way glow sticks work without a battery by mixing two chemicals together. This is done by having a tube inside of the main tube. Both tubes have a chemical in them and when you mix both chemicals in creates a glow. The crack you hear when you snap the glow stick is the small tube breaking and releasing the chemical it contains.

  19. Glow sticks work without a battery because there are two chemicals in the glow stick, on it a little tube in the glow stick and one in the main area of the tube, and by mixing them to together, you get the cracking sound and the part where the glow stick lights up. This happens because there are two different chemicals mixing together.

  20. Glow sticks work without batteries because of chemiluminescence a chemical reaction, that is why they don’t require batteries. chemiluminescence is a chemical that makes light without another energy light source. 🙂

  21. Lots of children think that Glow Sticks work by battery. I have always thought that, but from watching this video I now know that they are made of 2 chemicals. If you cut a Glow Stick carefully at the top, 2 parts will come out. One on the inside and the container on the outside.

    They both have 1 chemical in them. This makes them Glow. I always thought that all Glow sticks are different. What do you think/

      Bethany, I’m not sure if you have fully understood how glowsticks work. Please rewatch the video and think about the 2 different chemicals and what they do

  22. Glow sticks work without a battery because there are two chemicals in the glow stick that form a reaction, and this reactions is performed in light. However the color that is shown is determined by what type of chemical you put in. The crack sound you hear when you bend the glow stick is a tube breaking, and the chemical that was in there mixes with the other chemical.

  23. Glow sticks work from a chemical reaction when you bend the plastic tube, this causes two chemicals to fuse. So you don’t need electricity for these amazing chemicals.

    This makes a non electronic luminous glow.

  24. Glow sticks work from a chemical reaction, when you bend and shake the tube it causes chemicals to fuse Causing a chemical reaction.
    This may result with bubbles, changing colours and heat within the tube of liquid. Although the liquid has no electricity, you can even spill it onto something causing it to glow. This is pure science and it is amazing how it works.

  25. Glow sticks work without batteries because there are 2 chemicals that are in there. When you hear the crack that is when the 2 chemicals have mixed together. When they mix together it causes a chemical reaction and the reaction causes it to glow.

  26. Glow Sticks work because there are 2 chemicals in the stick so when you crack them the chemicals open up and the chemicals mix together and that’s why they glow.The chemicals that are in the vials have a glowing chemical in them.

  27. Glow sticks work because there are two chemicals in the container. When the two chemicals mix together they glow. the cracking sound you hear is the glass breaking and the two chemicals mixing together.
