Do you consider gyroscope an optical experiment?
One of the more jaw-dropping segments of the documentary comes when Bob Knodel, one of the hosts on a popular Flat Earth YouTube channel, walks viewers through an experiment involving a laser gyroscope. As the Earth rotates, the gyroscope appears to lean off-axis, staying in its original position as the Earth's curvature changes in relation. "What we found is, is when we turned on that gyroscope we found that we were picking up a drift. A 15 degree per hour drift," Knodel says, acknowledging that the gyroscope's behavior confirmed to exactly what you'd expect from a gyroscope on a rotating globe.
