Why does the soup in a cup say do not cook in microway but everybody does it
Is the container metal or have a metal rim? You arent supposed to put metal in a microwave because it can start a fire. And there is the chemical leeching issue someone else mentioned as well.
Even if the styrofoam doesn't melt completely, it will leak toxic chemicals into the soup.
The soup can speak? That's kind of worrying... :-)
Everybody does it is the MANTRA of the stubborn and immature childish individuals. Lets see the manufacturer has engineers, chemists etc but I no better WRONG.
