I said it was usless only because this technology already exists, and they are trying to reinvent it, to make it more cost effective for the average consumer. They say that hope for the consumer to be able to download plans for a cell phone and "print" one" Think about it. Imagine all the different polymers and gels and oozes and creams and whatnot it would take to make a cell phone. convectional methods have been established and proven. To be able to Print a cell phone at home, well thats just absurd. The cost and time of the unit and the printing process far outweigh the ease of which you can just buy a cell phone. Besides, not all of us have CAD training.

lol @ "please provide evidence that the evidence was destroyed!"

Par, if the above points are so important to you, why is the burden of proof all on someone else?

and remember, not everyone agrees on the definition of "proof" and "evidence" so you're just making a neat circular argument for yourself in the hope of stunning us all with your flawless, watertight, debate team logic.

how about you show me proof of where the molten metal came from, why it was the temperature it was, how much there was, why it stayed hot so long, etc. Don't worry, i got a good education, you can talk conduction, convection, radiation, specific heat capacity, exothermic chemical reactions, do your best. i am all ears.

according to wikipedia:

In fact, superheating of plain tap water, for instance in the microwave, is just as great a danger as when heating distilled water. In the popular Discovery Channel show Mythbusters, an experiment was conducted where distilled water was placed in a microwave oven for several minutes long enough to boil, but no convection (boiling bubbles) took place.[citation needed] When a contaminant (a sugar cube) was added to the superheated water, it had an explosive effect. However, this effect also occurs with normal tap water, as microscopic impurities (especially those which carry air bubbles) are needed for boiling to start.The dissolved impurities in tap water are not enough to inhibit the superheating.

The milk is denser than the water-based food coloring so the food coloring stays on and near the surface.

The soap reduces the surface tension of the liquid. The stronger surface tension of the surrounding milk then pulls the surface away from the weak, soapy region. The food coloring moves with the surface, streaming away from the soap. The surface will continue to stream away from a large drop of soap for awhile and produce that churning effect until the soap has diffused into the solution and been taken up by the fat in the milk.

Eventually all of the fat globules in the milk will be surrounded by soap and some soap will remain on the surface causing surface-tension-driven convection to stop.

Not really a tornado, per se. deathcow called it- it's a dust devil- a small, localized event caused by convection currents- not the storms and supercells that spawn tornadoes. It's not gonna' suck you up, Dorothy, but you probably should duck to avoid debris.
