Scattered across the world are a number of bewildering ‘mystery spots’ that appear to defy gravity — places where cars seem to drift uphill, and cyclists struggle to push themselves downhill.

Also known as gravity hills, these bizarre natural phenomena can be found in places like Confusion Hill in California and Magnetic Hill in Canada, and while they’ve inspired rumours of witchcraft and giant magnets buried in the countryside, the actual scientific explanation will have you questioning every slope you encounter from here on out.

There are reportedly dozens of gravity hills around the world, in the US, the UK, Australia, Brazil, and Italy, and they all have one thing in common — if you drive your car to the bottom of the hill and put it in neutral, it will proceed to roll back UP the slope.
