Maybe everyone in junior high was right: the clothes you wear really can make you cool! At least if those clothes are the new fabric developed in China with a kind of cooling system embedded inside. Plus: it’s National Chocolate Chip Cookie Day, so let’s find out about the largest chocolate chip cookie of all time.

New fabric could help keep you cool in the summer, even without A/C (Science Daily)

Summer, for many of us, is a months-long effort to get comfortable.

Fans, iced coffee, thinking cold thoughts… all nice but not really fully effective.

Air conditioning works, but it can be expensive and uses 10 percent of the entire U.S. electricity consumption, by some measures.


But maybe we’re thinking about this problem all wrong.

Maybe we wouldn’t need to cool rooms, if we were better able to cool the people in those rooms.

That’s the idea behind a new fabric that has its own cooling system built in!

A research team in China has invented what they call a personal cooling fabric.

The nanofibrous membranes they created actually transfer heat away from us and back into the surrounding air.

The outside is water-resistant, but the inside lets moisture from sweat out and allows air to circulate.

Now, is this alone going to replace A/C on a 100 degree day? Maybe not.

But if we’re all internally cooler, maybe we’ll be less likely to crank the air conditioner up on those hot days, and we’ll conserve some of that energy.

Which would be kind of cool.

Also: happy National Chocolate Chip Cookie Day to you.

Guinness tells me that the biggest chocolate chip cookie of all time came together in 2003 in Flat Rock, North Carolina.

It weighed 40,000 pounds and had a diameter of 101 feet.

Can you imagine the glass of milk you’d need to wash that down?
