Coffee Joulies are a kickstater project. On this website someone develops a projects with a funding goal set in place. This means if the goal is not reached by the amount of time allotted,  the creators aren’t expected to develop their project. This in turn allows for anyone to test concepts with minimal to zero risk.

Coffee Joulies has tripled sales of their initial funding goal. This eye catching creative concept has sparked an interest in the coffee connoisseurs. What are they exactly? Plop a few Joulies into your coffee, hot chocolate, tea, or any hot beverage as soon as it is poured and the Joulies will absorb the energy, keeping your drink the perfect temperature for longer.

To be more scientific, they absorb any extra thermal energy your beverage may have when it is served too hot. It will cool it to a more tolerable temperature three times faster than average. once cooled the stored energy the Joulies have will be exerted back into your cup making your warm beverage experience last longer!

The better insulated your cup, the better Coffee Joulies work.
