Science Demonstrations, The Hilarious House of Frightenstein, Watch Mr. Wizard
Demonstrations in Physics was an educational science series produced in Australia by ABC Television in 1969. The series was hosted by American scientist Julius Sumner Miller, who demonstrated experiments involving various disciplines in the world of physics. The series was also released in the United States under the title Science Demonstrations.
This program was a series of 45 shows (approximately 15 minutes each) on various topics in physics, organized into 3 units: Mechanics; Heat and Temperature / Toys; and Waves and Sound / Electricity and Magnetism.

Episode 32. Sound Waves - Sources of Sound
Frequency, pitch, how they relate to each other and correspond to musical notes.
Vibrating systems cause sound, sound requires a medium to travel.
Flexing different metal plates to produce different pitches.
Rotating plate with drilled holes and air blown through them – difference in sound between symmetrically drilled ones (music) and asymmetrically drilled ones (noise).
Vibrating a meter stick at different frequencies when different lengths stick out past a table.
Varying vrequencies rubbing a thumbnail across the milled edge of a coin, when tearing various pieces of cloth, using different files on wood, or riffling a deck of cards.
Human hearing range (16 Hz to 16 kHz)
Nodes in vibrating bars and tuning forks.
Notched stick with a spinning propeller.
Turing an orchestra – why they don’t use a piano.
Episode 33. Vibrating Bars and Strings
Bar mounted on a resonating chamber, mounted at 2 important places.
Second, "identical" bar, beats between two bars that are 1 Hz out of tune.
Beats between two tuning forks, one with rubber bands around the end of a prong to reduce its frequency.
Vibrations of a metal bar, shown on screen with a long pipe.
If you grasp a vibrating bar at the nodes it will keep vibrating, anywhere else it will stop.
Nodes on a vibrating bar are .224 of the bar length from each end.
Tuning forks on resonant boxes – transferring vibration from one to another (didn’t work).
Forming standing waves on a string, changing the number of nodes and antinodes at constant frequency and length by changing the tension.
Transferring vibrations from one vibrating bar to another through resonance.
