For example, I once had a student postulate that the water burns because water contains hydrogen, and hydrogen is flammable. Similarly, students have claimed that the water burns because water contains oxygen and oxygen supports combustion. Obviously both of these claims are incorrect. So in addition to teaching about density, miscibility and polarity, this demonstration has allowed me to reinforce to my students that the properties of an element change when it reacts to form compounds.
Water structure expert Richard Saykally, a chemistry professor at the University of California, Berkeley, notes the possibility that a plasma could be generated. Salt water in a W electromagnetic field "very likely makes some kind of plasma," he says.
Saykally dismisses the invocation of some special water structuring, which Roy and Kanzius suggest might contribute to the effect. Philip Ball , a consultant editor at Nature and author of the book "H 2 O: A Biography of Water," acknowledges that the new paper is "straightforward enough. Park , physics professor at the University of Maryland and author of "Voodoo Science," also has his doubts.

Technically I lied; burning water isn't really possible because it just evaporates.
But you can make a kitchen smell horrible and make a huge mess if you accidently let the water boil over the side of the dish, hit the burners, and evaporate on the stove top. Sound familiar? Don't feel bad: it takes talented people to "burn" water. Normally I like to focus on amazing dishes but to mix it up I want to focus on different things that can go wrong in the kitchen. Of course I will include tips on how to not let your dishes turn into failures. But the main point of this article is to point out that failures do happen and it doesn't mean anything about your cooking.
Not everyone can cook right off the bat, and I applaud anyone who attempts to cook. It can be easy or it can be very difficult. These three examples of what can go wrong are being told to encourage all of the new and old cooks alike, to not get discouraged but to keep on cooking!
Please note that these three are the things I struggle with the most. More experienced cooks probably have problems trying to get their souffl? Stop Burning Things! So maybe you've never burnt water, but I bet you've burnt something else. This may require the absolute immersion of the burning item in water so that the water makes a seal against oxygen being used by the fire or it may be used to cool the fire and allow the heat to be leached out of it by the cold water.
Firstly, if one of the substances that burn in water such as sodium or powdered magnesium is present, you might extinguish one blaze but start another. Technically, if you were to immerse a grease fire completely in water, then it would be extinguished due to lack of oxygen. In practice, it is a very, very bad idea to try and extinguish a grease fire with water.
Watch as this restaurant employee tries to put out a fryer fire with water:. When the water hits the grease, it creates little droplets of grease that are still burning, and which get sprayed everywhere.
Adding water to an oil fire is asking for a much bigger, much more dangerous blaze. Instead use a dry chemical fire extinguisher that is rated for class B or K fires.
Like this one or this one. Water can absolutely put out an electric fire , but only at the risk of electrocuting yourself and potentially creating other fires.
If you cannot remove the source of the electricity from a fire for example, by switching off the circuit breaker for the area before tackling it you should never use water on an electrical fire.
Instead, you should opt for carbon dioxide or powder extinguishers. Like this one.
