I have an idea for an experiment.
For the July 2nd, 2019 total solar eclipse, set up a pendulum to look for the Allais Effect near the path of totality, like in Argentina (Buenos Aires or San Juan). And set up another along the global antipode path in China (Shanghai). Though detecting the anomaly seems to be hit-and-miss, this would be to see if whatever may be causing it might also manifest at the antipodal path of the eclipse. If it's a gravity thing involving the sun-earth and moon-earth planes, it might, and seeing it on the opposite side of the world from the eclipse would lend itself to confirming the correlation.
None of us are going to do this, of course. But experienced experimenters in physics could do this, if an answer for the Allais effect is a worthwhile pursuit.
