…Grapes make plasma in your microwave?

And you thought all science projects were boring. This video walks you through the process of creating a glowing plasma ball in your very own microwave using only a standard green grape, a glass, and science. How does it work?

    “Grapes are full of electrolyte, an ion-rich liquid “grape juice” that conducts electricity. Each grape-half serves as a reservoir of electrolyte, connected together by a thin, weakly conducting path….the skin in this case. Microwaves cause the stray ions in the grape to travel back and forth very quickly between the two halves. As they do this, the current puts excess energy into the skin bridge, which heats up to a high temperature and eventually bursts into flame. At this point, the traveling electrons arc through the flame and across the gap, ionizing the air to a plasma (which itself can conduct electricity) and creating the bright flashes you see”.

It’s science.

…Pencil TVs are drawing past the competition?

Pencil TV

With the battle raging between plasma and LCD TV technologies, one player has stood back and watched the action from afar: Sharp Pencil Quality TV. Using a little glue and a pair of scissors (and of course a few pencils and paper), you can “break away from the tyranny of broadcast TV” and watch your favorite scenes over and over again, any time you please. Currently, there are only three titles featured, but look for many more in the future, as people adopt this un-technological yet highly personable television technology.
