[Each jar contains dozens of balls of floating light. The jars come with instructions on how to turn them on and off, as well as how to make them stay a solid color or have them change colors. If they are left out in the day 'off' the lights float like clear crystal and reflect rays of sunlight. HOWEVER, the one Tyrone Johnson receives does not turn off, and the lights will become increasingly happy, will do small-scale fireworks inside the jar, and essentially will just dance around in an attempt to make him happy. ]
