The following is the basic pattern for building cantilevered structures with Pennies. Although it looks trivial, we can build amazing structures with these pillars. All penny columns are ten pennies high, a "stack". Two side-by-side pennies held in place by a penny above them is called a "triad". Below is a stack with two triads resting on top. Now, I'll show you how to build a simple bridge. Carefully filling the space between with pennies, we create a one penny-span bridge. Repeating the process by putting an extra triad on top of each stack, we can create a two penny-span bridge. Although it looks weak, it will actually hold quite a bit of weight.
We can move on to a three penny-span bridge. And finally to six and seven penny-span bridges. Click "Next" to move on to "The Big Tower". Submit your amazing coin stacking pictures.

Kim Chee Fermentation. MIXED-PLATE BIOLOGY, HAWAIIAN STYLE: KIM CHEE FERMENTATION Submitted by: Jeanine Nakakura Kaimuki High School Honolulu, HI INTRODUCTION: The Korean government named kim chee (or kimchi) a national treasure.
A basic recipe for kim chee consists of vegetables pickled in a solution of garlic, salt, and red chili peppers. It is eaten year-round for its spicy taste and because it contains lots of vitamins C and B. In earlier times, during the fall, women made enough kim chee to last until early spring. In the winter, the kim chee would be buried in the ground, where it was warm, to keep it from freezing.

The mechanical parts can be seen in the picture above and include a fingering module (on the left) and a plucking module (on the right). Here is a close up of the plucker: Here is a close up of the teflon picks that actually contact the strings, and the solenoids (top, pink and blue wires) that power them, via the pluck rod linkages (middle). The fingering on the guitar is actuated by solenoids also (below), which connect to levers (above).
