Well, I guess I'll jump on the trivia bandwagon...only these questions will be science based. Same rules apply as in the other threads:
Answer the question correctly, and the quizzer will green light you to ask your own. If no one guesses it, you can ask another. Questions can have up to three parts (what is this, where was it made, and who made it, for example) You can post vidoe clues or picture clues, and let's try to keep it scientific (that shouldn't be hard, as science incorporates a wide spectrum of things). I will say one thing: be creative with your clues. You can simply post a picture of something and ask what it is, but where's the fun in that? I'll start.
Watch this video of two electronic devices playing a very familiar song:
YouTube - Zelda played on Twin Musical Tesla coils
The devices in question were invented by the same man who developed a frictionless, oscillating device that was claimed to have had powerful destructive properties. Who was the inventor, what was the oscillator referred to as, and by what principle did it function?
(hint: the name of the device has to do with seismic activity)
