I have my doubts that Pucs wouldn't bludgeon me in the teeth every time I took a drink from a glass containing them, but otherwise they seem pretty terrific. The stainless steel beverage coolers renounce the term "ice cubes", preferring instead to be known as "rechargeable thermal batteries" that give Scotch the chill without the dilution, and keep IPAs so cold they almost won't taste like a skunk took a piss in them.
Pucs are made of stainless steel, a gradual conductor that cools evenly and maintains its acquired temperature for an appreciable amount of time. Long enough for me to suck down a vodka soda, that's for sure. Add a straw to the equation and I bet I could finish a half dozen before the Pucs even realize they're no longer in the freezer.
In addition to keeping cold things cold, Pucs also serve as heat absorbers that make hot things less hot...but keep them from becoming not hot enough. Two Pucs will reduce the temperature of a steaming cup of coffee from 160 to 142 degrees F in about a minute. Then, as the coffee cools naturally, they'll return the heat they sucked up previously, allowing the coffee to hover in its drinkable zone for longer.
Like many kitchen tools, Pucs are precision machined from solid 304 stainless steel, and will not add or subtract any flavors from the drinks they chill. They also won't take on freezer odors. Or rust. Or degrade, chip, flake, or crack in any way. Hmmm, is that so? In that case, I wonder if I could buy an extra set to use in the miniature shuffleboard table I'm going to carve by hand one day when I get cured of laziness.
The Pucs campaign runs on Kickstarter through June 1, 2013, and production is a definite go, given they they have already earned 20 times their $2,500 funding goal in backer pledges. Pucs are packaged in sets of 6 and arrive neatly arranged in a solid Black Walnut or Maple case.
December 2013 Update: Pucs far exceeded their crowdfunding goal and is now available for direct purchase through the maker Onehundred's website--follow the link below.
