यूं ही नहीं फ्रिज के दरवाजों में लगा होता है चुंबक, चुंबक का सच सुनकर चो...

You may have seen in the old films that at that time the latch was framed on the doors of the fridge. But at that time, many children began to appear in front of the door to shut themselves in the fridge. The children were locked inside because of the closure of the door and they died due to suffocation. After several such cases came to light, the 1956 refrigerator safety act was passed in the US, in which it was mentioned that the fridge should be made, after which it can easily be opened from inside. The same act was passed a few days later in California. The reason behind this was that even if the children were locked in, they could get out of their own. After this the magnetic strip was started in the fridge doors. With this being the air-proof seal, doors opened easily. To test it, the doors were opened from the children inside the refrigerator and closed at the time.
