Re: Looking for demo ideas for TC

Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx>

This distance can be substantially increased by attaching a 10 x 10 inch
light aluminum plate to the top of the tube (serves as antenna) and a ground
clip with short wire to the lower end of the tube (ground).  This forms a
crude radio receiving circuit and extends the range considerably past the
hand-held range for the same coil.  This, of course, can lead to a
discussion of how radios work, tuned circuits, etc.

Clear argon and neon tubes can also be substituted which leads to an
interesting discussion question posed by the demonstrator, "Both tubes are
clear so why does one light up blue and one light up orange?"  This leads to
a short discussion on how atomic orbitals work, energy transitions, drop
back photon generation, X-ray generation, etc.  The demonstrator poses some
interesting questions and challenges the audience to provide an answer.

In this fashion learning and fun is had by all.
