what's up everybody welcome back tomorrow to our safety is number one priority and today we're going to be doing pretty cool experiment with glow sticks let's check this out so check this out this is icy water room temperature water and this is going to be boiled water just boiled it you see it steaming up it's a very very hot water boom just boiled it then we're going to activate three different glow sticks and put them in the water with the different temperature and let's see what happens as you can see right now they're pretty much the same brightness so this one is going to go in the hot water this one is going to go in the medium water and this one is going to go into cold water now let's see what happens so it's been about a minute look at these difference hot water super-bright medium water the same and the cold water it's almost not bad at all so now let's switch this out got this one and put it in the cold water and this one put it in the hot water let's see what happens it's turning off slowly and this one is getting way way brighter pretty insane huh let's give it a minute now as you can see in the hot water this go stick a super bright now this is the same and this one got less bright are now putting same huh how does this work now let's put this one in the hot water this one back in a cold and this one in the medium let's see what happens now look at this now this glow stick looks the brightest pretty incredible all of this experiment now put it back this one in ice and this one into the hot water and this one here you see it still looks like the brightest but it's cool enough so it's going to be less and less brighter in a minute and this one is going to get the brightest you can almost see right away how the light is switches this one is way more polite lady and this one is losing its brightness well hope you like this experiment glow stick and a hot water way more brighter than in the cold water or own temperature look at this difference amazing please do not microwave glow sticks because they will explode inside of a microwave or sometimes when you take it out they might explode in your hands and you don't want that chemicals on your face or hands success Wow I didn't want expeller stuff like that fun they
