The physics of microwave heating are well understood:For Ross,
slice a grape ( I have used the green variety ) in half stopping the cut just before breaking the skin on the far side. Put it into the microwave for 15 seconds or so ( not sure of your wattage )
voila plasma. The grape will flame out of both halves. I like to stand a few feet away while observing this one. The smell is a bit peculiar also. Fresh grapes seem to perform a little better.
Also you can superheat a glass or ceramic mug with water. This experiment will be potentially harder to reproduce. Just heat water for 3 to 5 minutes. If u open the door and the water is perfectly still and w/ out steam then take a long stick and move it. It will volcano erupt out of the glass. Obviously You need to utilize caution.
Now explain the physics of both of those experiments ! Woah- huu -boy !
I am not surprised that no one took up the challenge to investigate the proprietary fuel additives. The answer is available with some keen research as the study of fuel improvers (back in time to go forward) is related to contrail issues. The science here stops right where it gets interesting.
What do you think is unexplained?
And why don't you tell us about the fuel additives? Save us some research?
