Question: regarding the portable earthquake generator-why this and what would you want it to show people?

@859frcc45 Well I teach a lot of stuff about earthquakes at university, and we have a lot of earthquakes on Earth, but most people don’t really know what’s causing them. People know a lot about the dreadful damage they can cause and the disaster aspect, but not why. So my plan is to show people an earthquake – a very small one of course – and show what happens to the rock, how energy is released, what it looks like when it is picked up by a recorder, and how to interpret seismograms.
