His documentary , Soaked In Bleach , was amazing . Had a lot of evidence never talked about before . Completely debunking the mechanism of the shot gun and how it was found . How the release chamber where the shell fell out was on the opposite side of where the shell was with nothing in the way to ricochet it . I think I ' m on both sides , or could see both sides , but that documentary really makes you think . <| sep |> The problem isn ' t measurement precision . The thrust stand shown has a precision of about 100 uN , which is sufficient to find thrust at about 100 W . More sensitive instruments are likely possible , which should allow measurement at lower powers . Precision is fine , but only when accuracy is maintained . The counfounding effects that occur when power is applied to this thruster will affect the accuracy , showing thrust in the testing setup where there wouldn ' t be in a real world case .
