Tesla Oscillator

Known as the Earthquake Machine, Tesla built an oscillator that resonated at such a frequency that is shook the buildings around him, and he had to use a sledgehammer to destroy the machine as it wouldn’t shut down. Whether or not it could truly induce an earthquake is up to speculation. The guys at Mythbusters tested out this experiment with an oscillator of their own, but couldn’t reproduce the results, and they determined it ‘busted’ but did concede that buildings in Tesla’s time weren’t built to withstand the vibrations that today’s structures are, and that maybe it could happen.
