The MSM gave us to understand that the explosive involved could be triggered by a the kind of temperature increase we would expect from an overheating lithium battery. No one has yet specifically named a practical explosive which does this. You say PETN can be triggered by heating from a laser which is not the same thing at all. I like questioning official narratives, but am getting rather tired of this one. I'm not *that* interested to pursue the matter ad infinitum.
