Electrifying! Transform a simple lightbulb into a glowing, sparking plasma globe while teaching students about important topics, such as electric current, electron energy levels and photon emission. Simply screw a clear lightbulb into the Marekizer, and attach it to the tip of a Tesla coil. Turn on the Tesla coil and observe the electric sparks continuously “jump” from the lightbulb filament. Your students will be mesmerized by this simple plasma globe and will love to safely touch the glass bulb and feel the electric sparks on their fingertips. This demonstration can’t miss!
Concepts: Emission spectra, excited electron states, plasma globes, Tesla coils. Time Required: 10 minutes Materials Provided: Marekizer wire coil, two clear lightbulbs. Note: A Tesla coil is required but not included.
