Why wouldn't you want a coffee cup to be made from metal?
metal conducts electricity
metal conducts heat
metals have luster
metals can be made into a wire; they are ductile
Why are cords for toasters, televisions, and phone chargers made of metal wires?
metals are shiny
metals are good conductors of heat
metals are good conductors of electricity

Why is there always a plastic or rubber covering on wires for things that we plug in to electrical outlets?
because the wire is made of metal and metals conduct electricity, so it would shock you
to cover up the luster of the metal that the wire is made from
to make sure it doesn't attract to a magnet
so it won't get bent
