how can we drink a hot cup of coffee that is too hot to hold
Coffee Joulies, a Kickstarter project that raised $306,944 from enthusiastic supporters, was supposed to smooth the transition to the office. Drop one of the coffee bean-shaped capsules into a full cup and it would almost instantly absorb the excessive heat and cool down the coffee. Gradually, the non-toxic substance releases this trapped heat, which should keep your coffee warm for twice as long.
