  • A voltaic pile battery is used to light an LED.  This type of battery was the first chemical battery and was invented by Alessandro Volta in 1791.  This battery consists of two different metals.  Here copper United States pennies manufactured before 1982 were used and the source of Zinc was zinc coated washers.  Cotton paper is placed between the coins and wetted with an acid.  In this experiment the acid used was 5% acetic acid from household vinegar. The vinegar is the electrolyte<br />
Unlike the Leyden jar, the voltaic pile produces a continuous electricity and stable current. The order of the stack is copper, zinc and then paper.  This pattern is repeated throughout the battery.

  • This is an X-ray of a child's boot with electronics.  The batteries are mounded in the sole of the boot and the lights are placed along the sides.  A motion detector in the sole controls the flashing of the lights (light emitting diodes) as the child walks.  These types of boots rise many security issues when a child travels with them on an airplane.  The layout of the electronics and batteries is almost identical to a terrorist bomb placed in the sole of the boot.
