What are self-healing cutting mats made from?

When I was in graduate school, I took a seminar class from a chemist whose work in developing self-healing polymers was widely admired. I had seen these self-healing cutting mats in the MicroMark catalog, and always wondered what they were made of. So I asked him, in class. He looked at me like I’d grown a second head: “You mean to tell me you’ve seen self-healing polymers on the market? In a consumer product?” Later I brought him the catalog, and showed him the listing. He was stumped, and more than a bit dubious.

The Brookstone Beer Bulletin tipped us off to the fact that brewer Trumer Brauerei of Berkeley, CA, has created a fun video featuring a Rube Goldberg device made from Trumer product and paraphernalia. The Trume Pils Rube Goldberg Machine! Inspired by the Rube-Goldberg-Machine we were able to recreate the brewing process in a new way. […]

Frozen food dye in ice cube = cocktail color time-bomb

Frozen food dye in ice cube = cocktail color time-bomb

I love it when people get really, really serious about the preparation of drinks. Beverage and spirits writer Camper English is such a person. He has done some interesting experiments with freezing large pieces of crystal-clear ice at home (He reports boiling it first does not work), and freezing bottles of liqueur inside large blocks of it. His latest brainchild is this ice cube with a pocket of food color frozen inside, which is slowly released as the ice melts. The potential permutations on this trick are numerous: different colors in different cubes, different colors in the same cube, colors that react with citric acid in the drink and fade awhile after being released, etc., etc. [via NOTCOT]
