I’m really surprised by this finding. My assumption has always been that microwaves are pretty much inert to anything except the water molecules that they’re tuned to excite. If I just put a plastic container in the microwave with no water anywhere, will the micro particles still come out? Or is it really about what happens when hot objects are up against plastic regardless of what made them hot?
