Coffee Joulies Cools Coffee, then Keeps it Warm

These shiny coffee beans are a bit of a paradox that might warp you noodle like the age-old question about the chicken and the egg. Theses shiny beans are stainless steel that is polished and inside the shiny shell is some secret non-toxic material.

Coffee Joulies

That material is a solid at room temperature and when you drop it in coffee that is in the 140 degree range it absorbs the heat and the material inside melts. As it absorbs heat, it will cool your coffee three times faster than normal and keep you from burning your taste buds off.

The paradox part comes in the fact that while these things absorb heat and cool the coffee to start, once that material inside starts to harden it puts some of that heat back into your drink to make it warmer for twice as long. These beans are on Kickstarter right now to land funding and are well over the amount they need, but you can still contribute to the project if you want. A pledge of $40 or more will get you a set of five Joulies for yourself.
