SCIPP Electrifies COSMOS ! SCIPP Electrifies COSMOS ! SCIPP UC Santa Cruz Posted on Tue, May. 17, 2005 Students uninjured after power line falls on car By Sandra Gonzales Mercury News Four San Jose State University students escaped injury Monday night after being trapped in their car after a power line fell on it near the university. At about 8 p.m., the four were traveling in the car on South Sixth Street near East William Street when a tree fell, blocking the street and knocking down power lines, fire officials said. The lines struck a chain-link fence, a parked Honda Accord and a Chevrolet van, and one landed on the moving car. As the scene unfolded, a San Jose fire engine that happened to be nearby responded, warning the occupants of the Toyota Corolla to stay inside until PG&E could shut off the power to the line. The car's occupants were safe while they were inside the car, but could have been electrocuted if they attempted to get out before the power was cut. Once the power was shut off, the students safely left their car unharmed. The downed power lines, however, sparked a small fire on a nearby tree that was quickly extinguished.

SCIPP Electrifies COSMOS ! SCIPP Electrifies COSMOS ! SCIPP UC Santa Cruz Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle:Air is made of molecules. When they are ionized, they become charged and can conduct a current like an electrical wire. If there is a large current, it heats up the air and makes light. Thus, the sparks, flames etc are direct evidence for the model of atoms! Electricity in Air

SCIPP Electrifies COSMOS ! SCIPP Electrifies COSMOS ! SCIPP UC Santa Cruz An electron shooting out of the tesla coil hits lots of atom and knocks one of their electrons to a higher energy state. When the electron falls back down, it emits energy in the form of a photon, which travels to our eyes and we can see as light. What’s Going On?
