What laundry detergent use to have drinking glasses inside?

The laundry detergent that used to have drinking glasses inside was Tide. This was part of a promotional campaign in the 1980s.

The promotion involved placing a glass inside a box of Tide laundry detergent, with the idea being that the glass would remain clean and shiny even after being washed with Tide. This was meant to demonstrate the cleaning power of Tide.

While this campaign was successful in generating buzz, it ultimately drew criticism for being wasteful and contributing to environmental pollution.
