I know this sounds stupid, but I could have sworn Kool-Aid made this one thing that got cold by itself when you mixed it or something, without ice or using cold water, but I can't find the name for what it was called. Does anyone know what I'm talking about? Google yielded no results, but maybe some here might know or remember. This might be--I want to say--6 years or so ago?

Feel free to discuss Kool-Aid in general if it doesn't actually exist and I just imagined the product.
