MODEL RELEASED. Girl touching a plasma globe. She is nine years old. A plasma globe is a glass sphere filled with a gas at low pressure. In the centre is a metal ball charged with electricity. When the voltage is high enough,the electricity discharges across the sphere to the glass wall. The discharge ionises the gas along its path,causing it to emit light. The girl is touching the glass and this attracts the light beams towards the point of contact. The glass insulates her hands from the electric current | |
