This observation is to provoke thoughts and ideas. It’s best for you to do your own tests anyway you’d like to. If you want to take the time in measuring all the information you can but I think there are a few that are not measurable. I also know this is long but for those with eyes for details will see it’s not just refraction that’s occurring here. After watching this at normal speed please watch it at twice the speed and you can change the speed in the video setting.
