Basically : because it is something easy to mimmick in the privacy of your own home, : and it can even be done in your kitchen. Just unroll some plastic wrap : in a dark kitchen. The layers of plastic film stick together because : the material is a polar dielectric. When you pull the layers apart the : surfaces are left with unpaired charges in a nonuniform distribution : that is then equilibrated by surface discharges. When I form a bubble : in a polar dielectric liquid might I not produce the same effect? Funny you should mention this. Seth Putterman was talking with me about various unsolved "simple" physics problems. Specifically, how does a spark happen when you make "static electricity"? What are the dynamics that caused the macroscopic voltages get so concentrated out of low-energy large scale motion? : : Dick Blue : NSCL @ MSU -- -Matt Kennel mbk@inls1.ucsd.edu -Institute for Nonlinear Science, University of California, San Diego -*** AD: Archive for nonlinear dynamics papers & programs: FTP to -*** lyapunov.ucsd.edu, username "anonymous".
