Reply #73: The Bell Labs science project kits

[begin_within]

A series of kits produced by Bell Labs and given free to schools. In the "Solar Energy Experiment" you actually made a solar cell that could generate electricity from the sun. In "From Sun to Sound" you used a solar cell and built a circuit which made an audible sound. In "Speech Synthesis" (which was the most hotly desired kit) you built electric circuits which could produce sounds similar to vowel sounds made by humans. A lot of kids wanted that kit so they could make it cuss out the teacher, but then were disappointed when it only made vowel sounds. "Crystals and Light" contained experiments with growing crystals and looking at them under a microscope, and learing about crystal structure.
