NIKE Bounce Face x Apple Watch

NIKE faces for Apple Watch at first were exclusive to Apple Watch x NIKE editions but now they're open for anyone to download.

Something to amuse yourself during those endless, boring meetings in crowded, hot rooms.

You know the ones....


a pro with camera and video skilz way above my primitive capabilities (showcased in the video up top) demonstrates the Bounce face.

Details here and here.

Why does aluminum foil have one shiny side and one with a matte finish?


Ever think about that?

And wonder which side should face the food?

Below, longtime Washington Post columnist Robert L. Wolke explains it all for us.

First, a brief bit of history.

In the 19th century, Thomas Edison invented a phonograph machine, in which a sound-driven vibrating needle impressed grooves into a cylinder covered with a thin foil of the soft metal, tin.

In the 20th century, tinfoil was being widely used as a wrapping material for foods and drugs.

By the middle of the century, tinfoil had been replaced almost completely by thin foils of a different metal called aluminum.

Yet many people persist in calling aluminum foil "tinfoil."

We chemists get annoyed at things like that.

Get with it, folks!

This is the 21st century!

Now, about aluminum foil.

Aluminum foil is made by rolling sheets of 98.5 percent pure aluminum metal between pairs of polished, lubricated steel rollers.

Successive passes through the rollers squeeze the foil thinner.

Household aluminum foil is so thin (0.0005 of an inch) that the rollers can't handle it without tearing it.

The final rolling is therefore done on a sandwich of two sheets, face to face.

The outer surfaces emerge with a finish as smooth as the rollers, while the two face-to-face inner surfaces emerge with a matte finish.

Hence, a shiny side and a duller side.

When you use the foil, it makes no difference which side is up, down or sideways.

FunFact (from the same column, an answer to a different question): "Aluminum is the most abundant metal in the Earth's crust."

One more thing: a group of researchers from MIT in 2005 published the results of perhaps the most rigorous study ever performed investigating whether aluminum foil helmets serve as a protective measure against invasive radio signals.



one of the scientists in the lab.

I wonder if UK peeps find "aluminum" as amusing I find "aluminium," the British version of the word.
