Keeping your coffee warm

Ever wonder how to keep your coffee warm for hours on your desk while you’re busy typing your urgent document. It sounds strange but some metal beans known as Coffee Joulies can do wonders by keeping your drink warm for up to five hours. These beans actually cools down your cup of coffee to a drinkable temperature three times faster than normal rate, and maintain that temperature.
A team of inventors, Dave Jackson and Dave Petrillo added that “Coffee Joulies” metal beans absorbed extra thermal energy in the drink when it’s hot, and release those stored energy back into the drink to keep it at an optimum temperature as it begins to cool down.

Coffee lovers need not worry about toxicity of these metal beans, because “Coffee Joulies” contain a ‘special non-toxic material’ sealed within the beans’ stainless steel shells.
