Foil (song) and that shadow organizations are monitoring daily life, and he reinforces the conspiracy theory that the moon landings were fake. To conclude the song, Yankovic once again reinforces the greatness of aluminum foil, in this scenario putting a hat made of foil atop his head to avoid "thought control rays." The original song's instrumentation is carried over, albeit toned down a little to fit Al's singing voice, and the song contains elements of "minimalist electro-pop". Kevin O'Keeffe of "The Wire" observed that it is the shortest parody on "Mandatory Fun" as it omits the bridge and final chorus of the
Foil bearing Foil bearing Foil bearings, also known as foil-air bearings, are a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that no contact occurs. The shaft and foil are separated by the air's high pressure, which is generated by the rotation that pulls gas into the bearing via viscosity effects. A high speed of the shaft with respect to the foil is required to initiate the air gap, and once this has been achieved,
