We have one of those flat electric cooktops where the only part that gets hot is the "burner" itself which means we tend to leave things on the stove that do not belong there, sometimes even when the burners are on, including but not limited to plastic bags, plastic shot glasses, water bottles, trays including food that is already cooked and then proceeds to burn, and trays without food that get weird and warped, which have left a lot of weird looking melted things on our expensive stovetop
