Look how far he takes his topic. He would be a good jam jar designer or helper I bet.

Somewhat related tidbit.
I remember reading books on making mechanical vowel sounds in the 1800's so the topic interested me.
"Alexander Graham Bell in particular was interested in how Helmholtz used resonators to mimic vowel sounds. Due to not being able to read German, Bell misconstrued Helmholtz' diagrams as meaning that Helmholtz had transmitted vowel sounds over a wire, whereas Helmholtz was merely using electrical stimulation to keep his resonators in motion without manual intervention. Bell reasoned that if vowels could be transmitted, then consonants also should be possible. He tried, and failed, to reproduce what he thought had already been done by Helmholtz. However, Bell was later to say that if he had been able to read German he would probably have given up the task as impossible, but in the event, went on to invent the telephone using the harmonic telegraph as the basis."http://en.wikipedia.org/wiki/Hermann_von_Helmholtz
