Glow sticks glow in cold and warm water, but they last longer in warm water.
in the cold. best around 55 deg. F
Hot, but if you put them in water over 40 degrees Celsius then it will mess them up and they wont work right.
Glow sticks will show up better if you put them in the dark instead of leaving them in the light. Glow sticks are activated by breaking the tube inside and shaking them.
Glow sticks are exothermic.Exothermic is when heat/energy is released. And that is exactly what glow sticks do. but the energy being released is in the form of light.
No, phosphorus is NOT in glow sticks. Phosphorus is way to dangerous to be put in glow sticks. While a glow stick does have phosphorescence (meaning glow after illumination), it does not have phosphorus.
Glow sticks are a great way to enertain children of all ages. You can find a bulk order of these glow sticks at the website windycitynovelties.com/Glow-Sticks.
The better question is does a glow stick glow longer in hot or cold environments. Here since its a chemical reaction heat acts as a catalyst and speeds up the process. So in warm weather you'll get brighter glow that lasts significantly shorter then a glow stick in a cold environment. Funny enough if you cool down a glow stick enough (about -60 F) then the process will stop altogether.
Glow sticks are a chemical light.
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.
Heat them, for example by briefly putting them in hot water. They will glow more brightly, but won't last as long.
you dip them in hot water for about 30 seconds. Than your glow sticks should go back to glowing. :-)
Glow sticks are fun to play with you just take them out of the package and then snap them until they glow. But if you break the glow sticks then they will get on your friends night gown that you borrowed and then they will glow too.
The glow stick in the cold water will not glow as bright as the glow stick in the hot water because when you cool the glow stick down, the chemical process will slow down. The glow stick in the hot water will glow brighter but for a shorter period of time.
