Our goal of the class was to make a battery and bulb experiment. Don't know that is? Neither did I but it didn't involve hand sewing so I was pretty happy about that. I also thought it was funny that we were using the telephone wire that I bugged the AT&T guy to give us when I was younger for my wire bracelet business.
Here is my video explanation:

Tilt switch: The fish weight covered in steel wool and some electrical tape housed in a punched water bottle top would hit the screws to the left and the right completing the circuit and making the LEDs on the other side light up. It looked like a fuzzy Christmas bulb. I can't imagine trying to wear something like this but a simple on/off switch can replace this for adding to clothing and it can be done on a smaller scale.

Tips for any e-textile circuit project:
*Always mark your positive side of your LEDs, it's the longer side, but you couldn't tell that once they are split.
*Alkaline batteries are best.
*This project, as opposed to E-L Wire is very low voltage.
*A voltage meter is handing for troubleshooting. Out of the whole class, mine was the only one that didn't work. Apparently I did not hand wire wrap tight enough and with a few voltage tests and some pliers I was able to get my LEDs to light up.
*You always want to make a electronic swatch like this one that can attach and detach to your clothes for easy on/off removal to wash.
*Good water flow analogy (thanks our smart cookie teacher George!): the amount of water pressure through the pipes can be thought of as the voltage going through a wire. It's one way!
