1) Fill a cookie tray with water
2) Pepper the top of the water in order to *see* the movements of the surface tension
3) Carefully place a small amount of soap in the center of the tray
4) Watch the pepper scatter to the edges of the pan as the tension breaks

Salt water as a new alternative fuel source?

Upon igniting it continued to burn as long as the RF field was present in the water. At least the article seems to admit that this may take a lot more energy that what burning hydrogen would create. Take this article well salted!"
