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?
