Demonstrate the power of electricity and add a touch of science to any home with this Mini Plasma Ball.

Learn about the structural parts and electrical charges of atoms.

Plasmas, the fourth state of matter, contain ions or free electrons or both and conduct electricity.

Each kind of atom or molecule can gain or lose energy only in particular discrete amounts and thus can absorb and emit light only at wavelengths corresponding to these amounts. These wavelengths can be used to identify the substance.
