British scientists have managed to make water trickle up a steep slope.

The secret of their success lies in nothing more than shaking the surface the droplets were lying on - in this case a plastic plate.

When the plate is held at and angle and the vibrations are sufficiently strong, small drops can buck gravity and travel uphill - even mastering inclines as steep as 85 degrees.

Researcher Jens Eggers said it is likely the secret lies in the way the vibrations alter the shape of the droplets - and the forces acting on them.

The professor of applied maths said: "This is totally new. It's never been done before - and we're still not totally sure what's happening.

"As the shaking plate rises the drop is compressed, while it bulges upwards as the plate falls.

"If the shaking is vigorous enough to overcome the surface tension experienced as the drop is compressed, the drop will tend to lean forward, producing a net force which drives the drop uphill."
