I just fixed a cup of Theraflu, and noticed the directions state- “dissolve contents into 8 oz hot water. If using a microwave, add contents to 8 oz of cool water, stir briskly before and after heating.”
Why does the Theraflu care how the water gets hot?
I remember hearing a report that said mircrowaved water is different. Once micorwaved and cooled if it’s used to water plants the plants die. The report also said that observed under a microscope, the crystals of, previously boiled via microwave, water malform instead of coming together the way they ought to.
I can’t remember where I saw or heard this report so I’ll be very interested to hear the answers to this question.
(I already knew about the superheated + powder = deathly explosive potential!)
as mentioned the boiling readily starts at nucleation sites (small irregular points). in a metal pan on the stove top there are usually many scratches that are nucleation sites. in a glass (more likely) or ceramic container used in the microwave there are chances there aren’t many scratches or imperfections in the surface.
you can make a nucleation point to safely prevent super heating by placing a glass stirring rod (like a cocktail stirrer) into the vessel before you heat in the microwave.
as a last resort, you can also before touching the container or adding anything to it and after the microwave has stopped and you have opened it, put a long handled something into the liquid while wearing an oven mitt. do this only at arms reach. if you touch the container with your hand to take it out the boiling could occur and spill onto your hand. if you are close it could splash onto your face.
best to heat only for a time and power that you know will not make the water boil unless you take other precautions.
I’m only a HS science teacher, not a real scientist, but I just can’t imagine what would be the end use difference in water because it had been shaken back and forth by a certain frequency of light/radio. Water is energized all the time by other methods and no one claims this kind of thing for that. Are we then saying that water molecules that have encountered certain amounts of certain kinds of light are essentially NOT water as we commonly know it? They don’t have ten electrons? The electrons are in different orbitals and can’t fall back to ground state? The light has invented a new particle in between the water molecules that inhibits normal crystallization?
Microwaving water does nothing to change the very simple chemical composition of H2O.
It doesn’t ionize it or magnetize it. Though it does wiggle the electrons around during the process. The same thing happens when water is boiled on a stove, thought the process is a little reversed. On a stove, the heat excites the electrons. In a microwave, the excited electrons cause heat.
Otherwise the H2O remains H2O and all properties are the same.
As previously mentioned repeatedly, heating pure water in a smooth container without opportunity for nucleation will result in superheated water that will “explode” as soon as given a opening for nucleation such as introducing a spoon or a powder. (the same concept is at work in the diet coke/mentos explosion, but diet coke is not at 212+ degrees farenheit (100+ celcius))
