Cavendish Gravity Experiment Time Lapse Version 2

A few years back, I posted a video of my replication of the Cavendish Experiment, which both supported the idea that all objects exert a gravitational force on all other objects and allowed for the calculation of the universal gravitational constant. Unfortunately, due to some poor planning and environmental problems, my version didn’t go well. Thanks to those who pointed out some problems with the procedure ... I had no idea that that video would attract thousands of views, and numerous comments (some of which with lots of cursing!). This version of the experiment addresses some of the issues that came up the first time around. Right now, I’d still consider this the testing phase for developing a Cavendish apparatus I’m really happy with. In the summer of 2018, I’ll be building a large-scale apparatus in my home (where I can better control environmental conditions) which should allow me to make measurements precise enough to determine the value of the gravitational constant.
