When there's a heat wave during the fourth

This video likely worked because it is relatable and uses a popular trend of showing a humorous or exaggerated reaction to a common situation (heatwave during a holiday). The visual of the women eating popsicles is simple and effective.

Two women are shown eating popsicles during what appears to be a heatwave. They are dressed in pink outfits and are holding red, white, and blue popsicles.
