Creating an Aurora Lights Model for School Fair

Click For Summary
SUMMARY

The discussion centers on creating an Aurora Lights model for a school geography fair. Participants suggest using a cathode ray tube (CRT) filled with easily ionizable gas to produce vibrant light displays in a dark environment. This method is proposed as a more effective alternative to holograms for simulating the natural phenomenon of auroras. The conversation emphasizes hands-on experimentation and creativity in educational projects.

PREREQUISITES
  • Understanding of cathode ray tube (CRT) technology
  • Knowledge of ionizable gases and their properties
  • Basic principles of light and optics
  • Experience with creating models for educational purposes
NEXT STEPS
  • Research the properties and types of ionizable gases suitable for CRTs
  • Explore the principles of light production in cathode ray tubes
  • Investigate techniques for enhancing visual effects in dark environments
  • Learn about alternative methods for simulating auroras, such as LED technology
USEFUL FOR

Students, educators, and hobbyists interested in physics, light phenomena, and creative educational projects will benefit from this discussion.

hi all,

In our school there is a geography fair and i was just wondering weather it is possible to create aurura lights model.

i feel using a hologram a fairly good model can be made. But i want something more better. I hope some one can help me. :confused:

why don't u try using a cathode ray tube with some easily ionizable gas in it... place this apparatus in a dark room and lo behold, u have beautiful lights
 
i will try it out
