[Transparent Aluminum] was notably mentioned in the 1986 film Star Trek IV: The Voyage Home. Panels of ultra-thick acrylic glass were needed to construct water tanks within their ship’s cargo bay for containing two humpback whales and tons of water. However, the Enterprise crew, without money appropriate to the period, found it necessary to barter for the required materials. Chief Engineer Montgomery Scott exchanges the chemical formula for transparent aluminum for several sheets of the material from a manufacturer called Plexicorp. When Dr. Leonard McCoy informs Scott that giving Dr. Nichols the formula is altering the future, the engineer responds, “Why? How do we know he didn’t invent the thing?”
