The pepper is not floating, but is actually sitting on top the water. This is possible because water has a property called "Sufrace Tension" due to its cohesion.
When you put detergent in the water (or any other surfacant) you break the surface tension.

I agree with Mickey but pepper is too big to be treated like superficial-tensed substance...I think that little bubbles of air under it in fact are moving,acting like carriers for the pepper.
