Joulies: Make a Perfect Cup of Coffee or Tea

No caffeine, no creativity? Well, here’s something to perk you up:

Drop a couple Joulies into a hot mug of coffee or your cup of tea and magically your tongue-scalding brew is transformed to a drinkable temp (no more hot liquid burn lawsuits) and stays there for about three hours. It’s no trick– just pure science and a play on melting temperatures and thermal energy.

The Joulies are stainless steel discs molded wittily like coffee beans and filled with a “special non-toxic material… designed to melt at 140 degrees Fahrenheit”. Energy is released when the material begins to solidify again, distributing heat and keeping your drink at a steady, decent temperature.

Here’s how the inventors, who were design engineers, have put it:

First, they absorb extra thermal energy in your coffee when it’s served too hot, cooling it down to a drinkable temperature three times faster than normal. Next, they release that stored energy back into your coffee keeping it in the right temperature range twice as long.

Magical beans, indeed.

This clever Kickstarter project has exceeded its proposed funding target of $9,500 and raised $133,754+ from over 2,200 backers (that’s crowdfunding in action!). Something cool, clever, and simple that solves a common problem for people grabbing their caffeine on the go. Get that perfect sip– right out of the barista’s hands. Happy Monday, everyone!
