“Have you ever seen someone on Shavuos night pour the coffee grinds and sugar into coke instead of water? This way it has more caffeine and more sugar!!”
You don’t need these homemade inventions anymore, the companies do it for you. They now make Red Bull and other such drinks. IMO, these drinks would have been made illegal due to their content, by the FDA; maybe s/o in the gov. was paid off to allow it through.
