This video is about Gravity Hills and tries to explain how they work, if you never heard about the subject, a Gravity Hill is a illusion created by nature in which a road appearing to go up actually has a downhill slope. I also approach other illusions like the Ames Room and the impossible motion ramp.
If is not clear in the video, I'm Portuguese and Braga is my home city, this road is quite a tourist attraction and almost every day you can spot people with their cars in neutral trying it out, to see in which direction the car goes.
If after the video you still have any doubt about the subject just ask in the comment section and if you like videos about science, do visit my channel:
