@trwnh it's not really a material property, it's caused by the metallization on it
the LDPE that the bags are made of turns into HDPE, i think, caused by the sparks that the metal gives off in the microwave
@LottieVixen @trwnh i don't think it's any worse than the grape thing, really
@trwnh @LottieVixen yes
this has to be one of the most well-known microwave things right? https://www.youtube.com/watch?v=wCrtk-pyP0I
@trwnh i guess it'd work on the big ones too but it'd be kinda hard to fit those in the microwave
