  • Take a look at this Victorian illusion.

  • Most people think that the top hat is taller than it is wide.

  • In fact, the two distances are exactly the same, and the illusion is caused by people perceiving horizontal lines as being shorter than vertical ones.

  • The same illusion makes people underestimate the width of short wide glasses, and so they tend to pour more liquid into the glass.

  • In fact, research from Cornell University shows that people pour 30 percent more liquid into short wide glasses than tall thin ones, and even experienced bartenders pour 20 percent more.

  • So, if you want to cut down on your drinking the easy way, go for tall thin glasses.

Take a look at this Victorian illusion.
