This project will automatically turn on an EL panel with a mercury tilt switch. By extending your arm or raising it slightly, the mercury will complete the circuit, resulting in the EL panel to light up brightly whether solid or blinking. Give this project a try, and you'll be amazed.
Step 1: Materials
1. EL Panel w/ AA-powered AC Inverter  *these may be separate or if you'd like to have solid EL panels, soldering might be required)
2. Mercury Tilt Switch 
3. Velcro strips [4-6 pairs]
4. 1.5V Button Cell--LR44 / AG13 
5. Electrical Tape
6. Armband 
[#] indicates the amount needed
Step 2: Placing the Button Cells
Next, use the piece of electrical tape and "loop" it so that both sides are sticky.
Stick it to any side of the button cell and place it in the battery compartment--with the negative side of the button cell touching the spring of the battery compartment.
Repeat these steps for the second battery compartment.
*The negative side is the side without writing!*
