Why water splashes: new theory reveals secrets

New research from the University of Warwick generates fresh insight into how a raindrop or spilt coffee splashes.

  • Reason why raindrops and spilt coffee splash revealed by University of Warwick research
  • New theory uncovers – for first time – what happens in space between liquid drop and surface to cause splash
  • Microscopic layer of air – 50 times smaller than a human hair – trapped between liquid and surface can prevent liquid spreading on surface
  • Scale comparable to a 1cm layer of air stopping a tsunami wave spreading across a beach
  • Research published in top Physics & Mathematics journal

New research from the University of Warwick generates fresh insight into how a raindrop or spilt coffee splashes.

Dr James Sprittles from the Mathematics Institute has created a new theory to explain exactly what happens - in the tiny space between a drop of water and a surface - to cause a splash.
