Coffee Joulies

 

If you have ever been burned by an overly hot cup of coffee or tea, then this product may be for you.

The brains at Kickstarter.com have made available an interesting device that uses thermodynamics in a very practical way.

These little stainless steel beans are filled with a non-toxic substance that melts when submerged in any liquid over 140 degrees Fahrenheit (60 degrees Celsius). The interior substance draws in the excess heat from your beverage and stores the heat, helping to keep your drink warm longer.

 

The Coffee Joulies effectiveness is greatly increased when used in conjunction with insulated cups or a vacuum thermos. The addition of these beans to your thermos packed drink can help keep the temperature ideal for up to 5 hours.

Head on over to Kickstarter.com for more information, or to purchase the starter pack for $40.
