Coffee Joulies keep drinks hot

If there is one thing that most coffee drinkers do not like, it has to be a cold cup of dark stuff and in the winter, it seems that keeping the coffee warm even for a few minutes is an impossible task.

However, thanks to Kickstarter, the online fund raising platform Coffee Joulies has managed to attract funding of over $300,000 and these large metal beans will soon be going into production.

So what are Coffee Joulies? These coffee bean shaped things are made from metal, they are placed into the cup before the coffee and absorb the heat, this warmth is then gradually returned to the beverage over a five hour period!

These are the features and specs for the

According to a company spokesperson, ‘This material is designed to melt at 140 degrees Fahrenheit, and absorbs a lot of energy as it melts. This is how Joulies cool your coffee down three times faster than normal.

‘Once it reaches this temperature, the special material begins to solidify again, releasing the energy it stored when it melted. This is how Joulies keep your coffee warm twice as long.’ they added.
