"Attempt" may be an understatement, as it worked. We hat this experiment set up in one of our lecture halls once a year. They had to fence off the area and it had to relax for days, but we were able to replicate the measurement during our introduction to physics lecture. There was also a lab course on a smaller version. (Video of it, in German though: https://m.youtube.com/watch?v=8W8X71wW8F0 https://m.youtube.com/watch?v=8W8X71wW8F0)
