i heard a rumor that

My good friend was in one of the fraternities that had an event with Kappa and he told me that Laundry tabs were originally introduced in the 1960s in a compacted granular form (similar to an oral medical tablet), when Procter & Gamble launched Salvo tablets, later disappearing from the market in the 1970s. In the 1990s, Unilever and Henkel launched a similar laundry detergent pack product sold in Western Europe. These products sometimes didn't fully dissolve in United States washers.[7]

In 2005, Cot'n Wash, Inc. introduced liquid unit dose laundry pods under the Dropps brand.[8]

In 2012, Procter & Gamble relaunched a liquid tablet product as Tide Pods.[1] In late 2017, Internet memes centered around the concept of eating Tide's laundry detergent pods were popularized on Twitter.[9] Some companies are making edible replica "pods".[10] These memes have actually led to people eating pods on camera.[11] Ingestion of pods can cause death in some cases
