Water drops bounce into action

What happens if you let a drop of water fall gently onto a water-repelling surface? Physicists in France and the Netherlands who tried the experiment were surprised by what they saw. They found that a violent, ultra-fine jet of water emerges from the drop, moving at up to 40 times the drop's initial impact speed.
