What else can I help you with?
How can you make glow stick last longer and why?
you can make a glow stick last longer by putting it in hot water. the heat makes the atoms inside move around faster which keeps the glow glow longer and brighter
How can you make things glow in the dark at home?
Get some glow-in-the-dark paint, or self-adhesive sticker material.
What is praise of science and what is critical of science?
Data: The cold water was at a temperature of -8 degrees Celsius. The hot water was at 80 degrees Celsius, and the room temperature water was 23 degrees Celsius. Our observations when we put the glow stick in the cooler water, the glow sticks light intensity decreased the longer the glow stick sat there. After a much longer period of time the light of the glow stick completely went out. When we put the glow stick in the hotter water the light of the glow stick increased significantly, the color of the glow stick became a much brighter color pink. At the room temperature the glow stick in the water when we broke it the color was light but not as bright as the one in the hotter water but not as dark in the colder water, but it stayed the same as when we broke it.Conclusion: During class, we have been conducting our science fair experiment on glow sticks and there light reaction to hot, cold, and room temperature waters. We secured each glow stick in a glass of water at temperatures of 80 degrees Celsius (hot), -8 degrees Celsius (cold) and 23 degrees Celsius. (About room temperature). The environments that a glow stick is keep does affect the way the chemical reaction between the dye, ester, and hydrogen peroxide, in which how bright the energy is giving off during the reaction. Our hypothesis was; if I change the environment temperature of the glow sticks then when secured in a hotter environment the glow sticks light intensity will be brighter. This was our hypotheses because I thought if the chemicals during the reaction we heated, and the warmer the water is the faster the bonds move. It is easier and faster to mix the chemicals more quickly in result the energy of the chemical reaction would produce more light. My hypothesis was supported. When we secluded the glow stick in a hotter temperature the glow stick became much bright, and over time the glow stick even changed to lighter color pink. In some cases there could have been some errors, perhaps if the glow stick had already had the capsule broken or the glow stick was out dated, and even if the water was too cool or not cool enough. You could defiantly use this information learned in the real world. That many things that can result in chemical reactions and you can learn that the glow sticks chemical reaction, it shows the energy giving off by the glow sticks combinations of chemicals. I would like to learn more about what's in each chemical, and how each of them reacts in order to produce the light? by; sarah.+++.Well done, Sarah, and certainly science, but I am not sure how it answers the heading question! I was interested to see that the temperature seems to affect the colour as well as brightness. I have a question though: how did you keep the water liquid at -8ºC? In a formal report you would add such details so that if anyone wishes to repeat your study they can ensure they are doing so correctly..I do see that you considered if using a used or out-dated glow-stick could give errors, and error-reduction is an important part of any scientific experiment. Here is a classic example:.Have you read how the pioneering physicist, Joule (after whom the unit of energy is named) established the link between mechanical and heat energy, hence the foundation of the law that energy can only be transferred or converted? He repeated the test, using a weight-driven stirrer in a cask of water, many, many times, and tried to find and reduce the errors as much as possible, to obtain a result that was as accurate as possible. (The water is warmed slightly by being agitated, showing the mechanical energy used to rotate the paddles is converted to heat energy in the water. By very careful measurement and calculation Joule established the conversion numerically.)
What materials did artists use to make the pages of illuminated manuscripts appear to glow?
the awnser is bright pigments and paints
If a glow stick has gone out and you put it in the refrigerator will it glow again?
Yes it will. All you have to do is keep it in the freezer for about an hour, then crack it again and it'll begin to glow. It will not glow as bright as it did the first time though.
Why do highlighters glow?
Highlighters glow because of the phosphors that the black light contain and because of its chemicals in it.
Do highlighters glow under a black light?
Yes, some highlighters contain fluorescent materials that can glow under a black light due to their ability to absorb and re-emit light at a different wavelength. It is important to note that not all highlighters will glow under a black light.
Does blue highlighters glow brightly under a black light?
No, it doesn't.
Do highlighters make schools better?
yes , highlighters make schools better
How do you make highlighters?
Fluorescein.
What makes a yellow highlighter glow?
Yellow highlighters contain fluorescent pigments that absorb and then emit light at a longer wavelength, making them appear to glow under ultraviolet light. This phenomenon is known as fluorescence and is commonly used in highlighter inks to make them stand out.
What chemicals make a highlighter glow?
Highlighters glow under black light due to the presence of fluorescent dyes, typically compounds like pyranine or rhodamine. These dyes absorb UV light and re-emit it as visible light, creating the glowing effect.
How can I get glow sticks to glow again?
To make glow sticks glow again, try placing them in hot water or in the freezer for a few minutes. This can help reactivate the chemicals inside the glow sticks and make them glow brighter.
In Mimi's desk drawer there are 7 yellow highlighters. There are 2 more pink highlighters than yellow highlighters and there are 11 more blue highlighters than pink highlighters. How many highlighters?
27 highlighters in total.
How can you revive glow sticks to make them glow again?
To revive glow sticks and make them glow again, you can try placing them in hot water or using a hair dryer to heat them up. This can help reactivate the chemicals inside the glow sticks and restore their glow.
Are glow sticks made with water?
There is no water used in the making of a standard glow stick, it is simply a chemical reaction between two chemicals. Water can however be used to make a glow stick brighter.
What is a Question for Glowing Water?
well I think a good question would be, what is in the highlighter that gives off its glow
