Ancient Chinese Earthquake Detector

Ancient Chinese Earthquake Detector

Sketchycat
A very ancient earthquake detector, the slightest movement would knock the pole over knocking a ball and showing which direction it came. Knock the poll over, ( i didn't really feel like making an earthquake machine ) to see where the quake would of came from, this actually saved tons of people once long ago. #ancient #china #chinese #detector #earth #earthquake #machine #nick #quake #seismograph #sketchy_physics #sketchycat #sketchyphysics
