Plasma is the highly energetic fourth state of matter, the problem is however, we don't get to see it very often! Unless you have a plasma ball!
A plasma ball contain gases that become a plasma when energerized by electricity. While these are a popular decorative and fun item, one must be careful not to put them too close to other electrical devices, or place metal objects on the glass. The plasma ball creates a field that can make electronics malfunction, and the glass can overheat when touched with metal.
