If you bottle up a gas and try to image its atoms using today's most powerful microscopes, you will see little more than a shadowy blur. Atoms zip around at lightning speeds and are difficult to pin down at ambient temperatures.

Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today's smart phones process more data, but they still weren't built for being shoved into back pockets.
