A Flat Earther spent a staggering $20,000 on a DIY experiment that accidentally proved the planet is round.
He was in the middle of filming for a Netflix documentary titled Behind the Curve when he realised his pricy mistake.
Seeking to disprove the mass of research led by NASA experts, he explained the particulars of the DIY experiment using a laser gyroscope.
Yet, in a humorous and expensive turn of events, no light could be seen, causing the Flat Earther to mutter an awkward 'interesting' after the mistake.
According to Unilad, one Instagram user claimed: 'I bet he still won't accept it.'
Another said: 'Something oddly satisfying about watching a simple opinion dissolve in the face of non-rigorous methods lol.'
The failed experiment has since gone viral on Reddit, with people noticing that even after the experiment, the Flat Earther kept using 'mental gymnastics' to claim his conspiracy theory was still correct.
One person wrote: 'I've seen that clip many times but have yet to see his explanation as to how that happened.'
