There are many very simple ways just to prove immediately that it's an optical illusion, but for some reason these people just want to live in a lie and think it's a hill with messed up gravity.

While I completley agree that the effect is caused by an optical illusion I am still struggling to think of a simple method to demonstrate that it is not caused by a "local gravity distortion".

A pendulum or a bowl of water are easy ways to normally find a true level and show the direction of incline, (provided you aren't accelerating or decelerating), however in both cases a believer could argue that they are both just being pulled that way by the "backwards gravity".

(Also, sorry for replying 6 months after you originally commented.)
