PiezoElectric Rocks

$4.99

These quartz rocks generate light and sparks when they are struck or rubbed together. This is due to the principle of piezoelectricity. When the crystals that make up the rocks are subjected to mechanical stresses, they produce electricity. This principle is used in reverse in many electronic devices. When provided a voltage, crystals in electronic devices oscillate at a particular frequency based on the size, shape and composition of the crystal. These crystal oscillators are so accurate, they are used to measure time in wristwatches and clocks.
