Buttons on pedestrian crossings are often just placebos — they don’t actually change the traffic light, they just create the feeling that you’re doing something. The same goes for the door-closing buttons in elevators, which are usually disabled unless used by a firefighter with a special key. Grocery carts? Those carts are deliberately made big so you feel like you’re buying less and picking up more stuff. The stripes on toothpaste? That’s pure marketing — they don’t make the toothpaste more effective, they just look pretty so they can sell more. Those little pins on carts aren’t random; they’re there to hang bags on, so that eggs and bread don’t get dented. Even thermostat knobs can be fake — they just prevent excessive interference with the real system! #a4 #space #360 #interestingfacts #howtoloseweight #interesting Animation created for Bright Side. ---------------------------------------------------------------------------------------- Music: Epidemic Sound https://www.epidemicsound.com/ Subscribe to AdMe: http://goo.gl/DgUonf ---------------------------------------------------------------------------------------- Stock materials (photos, videos and others): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru ---------------------------------------------------------------------------------------- More cool articles and videos on http://adme.ru/
