Great concept, but it wasn't Kool Aid. It was Flavor Aid.
The cult that inspired "drink the Kool-Aid" didn’t actually drink Kool-Aid

Made by Jel-Sert, Flavor Aid appeared in one of the first newspaper reports on the massacre. The claim is repeated in the 1982 book Raven: The Untold Story of the Rev. Jim Jones and His People. And surviving witnesses said that Flavor Aid was the drink used, not Kool-Aid.
