What I think is happening to produce the deterioration of the plastic bottle containing the ECCO fuel is nuclear reactions produced by the nuclear active agents residing in the ECCO fuel. This agent can then move forward to penetrate the plastic and react with the plastic in the second plastic container. and then pass through that second barrier and react with the seal of the neutron detector tube.
Georges Lochak and Leonid Urutskoev attempted to characterize this agent and found that the agent passed through aluminum but would not pass through iron, a magnetic material.
MFMP can use the deterioration of the plastic bottle as an experimental probe to see what materials this agent will pass through and which materials will contain it.
John Fisher found that this agent was constrained inside a rubber seal in his experimental setup and the activated seal produced tracks in CR39 detector. He also saw CR39 tracts in the steam coming out of a electrolysis experiment presumably produced by the LENR active agent.
