Kirlian plasma globe

Close up of a Kirlian plasma globe, a type of electrical discharge tube sold as an executive toy. The central wand is kept at a high electrical potential, so that a large electric field exists across the rarified gas within the glass sphere. When the outside of the sphere is touched (changing the local electrical potential) streams of charged particles flow across the gas, ionising it and causing shifting, glowing patterns. The effect was discovered by the physicist Nikola Tesla and and is used in Kirlian photography; it is known as the Tesla or Kirlian effect
