Coffee joulies

Don't you hate it when you leave a delicious cup of tea to steep, and
you either wait too long and the tea is too cold, or you don't wait long
enough and the tea nearly burns a hole through your tongue?
Well, two friends (both named Dave) have just come up with the perfect
remedy for this problem: coffee joulies! Coffee joulies absorb thermal
energy from coffee or tea that's too hot, thereby "cooling it down to a
drinkable temperature three times faster". Then, they release the stored
thermal energy back into your mug to keep your coffee or tea at that
perfect temperature for twice as long! How neat is that?? 


Thank you so much for the lovely comments! I read and value every single one.
