What are some interesting psychological experiments?

 This is called the Napkin Experiment.

Next time you have a party at work or home, try this and see for yourself.

The first time, put these common/regular napkins in a bunch for the guests to use.

Watch them abuse these napkins, just pulling them out as they please, in any numbers. Most people will take more than one. They will trash this napkin without care and get more as needed.

The second time, use these instead. Nothing really fancy here compared to the previous napkin - just a different, bright color.

Watch the difference this time. People will treat them as special, being careful to just pull one at a time. They will also preserve this napkin longer.

People automatically assign importance when something appears different or fancier than what they are used to.

This is also the same principle where well dressed people are usually treated better.

Be different, in a good way, to be treated special.

What are some strange but fascinating scientific experiments?

 A small team of researchers from Spain and Mexico made a discovery, almost by accident, which

was later published in the renowned journal

Physics Review Letters .

Thousands of cubes randomly poured into a glass align themselves perfectly when the mixture is subjected to "oscillating rotation," that is, alternately accelerated clockwise and counterclockwise.

The researchers poured 25,000 plastic cubes into a transparent cylinder. They then tested various shaking techniques to determine which resulted in the highest compaction of the cubes.
They found that alternating rotation (left-right-left-right) worked best. However, the individual rotations had to be performed at high speed.
This caused the cubes to align themselves from top to bottom, forming concentric circles in each layer.

At an acceleration of 0.52 g, the pile of cubes reached its maximum density after 10,000 alternating angular impulses.
This seems to work significantly better than a simple "jerking," because at a state of medium density, the latter causes the cubes to wedge themselves together and remain stuck.
If the rotational impulses are too slow, the compaction and alignment of the cubes could potentially take years.

The researchers now hope that their findings will open up a potential new way to compact materials during the manufacturing process.
