The energy supplied from imposed KE in the atomization overcomes the probably positive entropy change of a system far from equilibrium since there was no peroxide to start. All that is needed is a possible mechanism and the micro surfaces seem to provide that. Static electricity can be formidable albeit difficult to control and direct. | |

We also speculate about the nature of the mechanism responsible for these observations." I get upset when a proper energy balance is ignored; someone has to squeeze the rubber bulb. The chemistry is exciting tho. | |
