Conductive Liquid

Elie Zananiri and I decided to make a fluid that would allow us to create liquid circuits. We tried many different combinations of the materials: water, oil, salt, powder graphite, and glue. The best combination was water, salt, and graphite, which resulted in a mixture that gave a steady reading of about 100 ohms. We used the liquid to create both a drawn circuit and an irrigation circuit.

Teach-Shirt

A concern of mine for the developing world is how to deliver teaching materials. I had an idea for t-shirts that have information printed on them in a way that makes it viewable while being worn. This way the person could study randomly through out the day. The shirts could have printing on all 4 sides: front, back, inside front, inside back. Each side would have a different subject matter, perhaps mathematics, science, history, and art. The teachings would be designed for each specific area to which they were distributed.
