I love kitchen science experiments, here is the explanation: When you add a drop of soap, you greatly reduce the surface tension of the water near the point at which you add the soap. Initially, this causes a repulsion of the pepper particles and the particles tend to follow the high surface tension areas.
yeah we did that in science classaha!:-P
I've never seen that before! Really cool.
that video was repellant (sorry .. I couldn't resist)
yes, i guess thats what happens when you make a video in 30 minutes!
