Aluminium foil foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner. The continuous casting method is much less energy intensive and has become the preferred process. For thicknesses below , two layers are usually put together
Tin Woodman in any of the film adaptations (unless they are satirical), the Tin Woodman wonders what he would do if he ran out of oil. "You wouldn't be as badly off as John D. Rockefeller," the Scarecrow responds, "He'd lose six thousand dollars a minute if that happened."
