It says why in the quote, to “cool” it. I have never tried it myself but it seems like it would be effective for that purpose.

your comment in the context of jello makes me think of Cool Whip, but that takes us to "You must whip it: Whip it good!" and here we are full circle.

		I've heard (though cannot find any supporting references) that Devo's song "Whip It" referred to "whippets", nitrous oxide cannisters which could produce a brief but euphoric high. <https://www.webmd.com/mental-health/addiction/what-are-whipp...> Context was a stage performance (not by Devo) roughly 20 years ago, referring to late 1970s / early 1980s youth culture. The song itself was released in 1980: <https://en.wikipedia.org/wiki/Whip_It_(Devo_song)>
