this is for my daughter's science homework.she has to bring in something that will prevent aluminum foil from rusting
Rust is a fairly specific term and it applies to the oxide coating formed on ironAluminum passivates by forming a layer of Al2O3 on the surface of fresh aluminum metal almost immediatelyYou basically can't keep it from forming unless you remove the aluminum from exposure to oxygen, which is a bit tough for a school project.
