Why does aluminum explode in the microwave?
The FDA reiterates that food completely covered in aluminum foil should not be put in the microwave here . The electric fields in microwaves cause charges to flow through metal. Thin pieces of metal like aluminum foil are overwhelmed by these currents, causing them to heat up so quickly that they can ignite.
Can microwaves penetrate aluminum foil?
Aluminium is a metal so cannot be penetrated by microwave energy. This means that any microwaves are only absorbed through the top (open) part of the container to a depth of only about 3 cms. The aluminium effectively shields the sides and base of the of the food from overheating.
