Hi Folks!

You might want to check out this incredibly well done and complete list
of science experiments and demonstrations, most with pictures and clear
descriptions of how to duplicate various effects and phenomena from
electromagnetic can crushers to sawing a laser beam...its really
excellent;

http://www.physics.umd.edu/deptinfo/facilities/lecdem/demolst.htm

Some of the experiments which relate to KeelyNet subjects include;

Tesla coil;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k7-61.htm

Electromagnetic can smasher (magnetic pinch effect);
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k2-62.htm

Thomsons' coil (reminds me of the Stevens F/E Coil);
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k2-61.htm

Eddy currents to move an aluminum can;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k2-45.htm

Lenz law and slow falling magnets;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k2-42.htm
(this can be demonstrated also by buying a tube of aluminum foil and
just dropping a magnet down the center, it will fall slower than outside
the tube due to eddy currents and Lenze law)

Magnetic braking effect of rolling non-magnetic metal rods into a
magnetic field;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/k2-41.htm
(The defunct Tesla Society had a magnetic brake which consisted of a
large copper disc spun to high speeds, when a strong magnet was placed
next to it, the disc stopped INSTANTLY...this has interesting
possibilities for Dean type inertial drives where you have to stop and
start mass instantly)

OOOHHHH BAAABBBYYYY! Check this out and bear in mind the Steven coil;

Series Capacitors;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/j4-03.htm

Electrostatic discharges to various radii spheres;
http://www.physics.umd.edu/deptinfo/facilities/lecdem/j3-07.htm
(when visiting Peter Kelly's lab in Georgia he showed me a series of
spheres mounted on a board and separated by ever larger distancs, small
spheres at the bottom and very large ones at the top...he said this was
one of Townsend Browns mechanical ways to create high voltage...that is
what this experiment shows...he also had a 3 foot aluminum disc that was
used in Browns experiments, it was fat in the middle, like a
saucer..very interesting to see and handle some of the artefacts used in
Browns experiments..)

version of the 'wasserfadden';

Totally cool demo of solitons (standing waves of matter);
http://www.physics.umd.edu/deptinfo/facilities/lecdem/g4-41.htm
Two solitons can be created at different positions in the tank. If one
is pushed toward the other, they will attract each other if they are in
phase, and repel each other if they are out of phase. One soliton can be
pushed toward a second out-of-phase soliton, causing the second soliton
to move down the tank.
