Want to collect more money? Make eyes!

A funny and instructive experiment was conducted by scientists from the University of Virginia.

For a month they meticulously considered donations in one of the museums, supplying the box with photographs of the nose, mouth, chair, and eyes.

Eyes won by a large margin, almost doubling the donations by half.

So comrades, if in your life you have to collect coins for some business, then remember this note and mow money more efficiently.
