How do massive icebergs floating in the ocean suddenly topple over on their own?
These are called icebergs, and approximately 90% of them are hidden underwater. When the ice beneath slowly melts, their weight becomes unbalanced, leading to a moment when the entire iceberg loses its balance, and within seconds, a mountain of millions of tons of ice topples with a loud noise.
When a large building is demolished in the middle of a city, the dust and debris can become a major nuisance for residents. But China has found a remarkable solution. A massive dome is installed atop the building, preventing dust, dirt, and debris from flying outside. While the machinery inside keeps blowing, the building itself isn't bothered by excessive dust or the people outside.
Look at Finland, where parents put their young children to sleep in the snow. This sounds dangerous, but it's considered perfectly normal there. In fact, the cold, fresh air strengthens their immunity. For this reason, many parents in Finland wrap their babies in warm clothes and let them sleep outside in strollers, but this should only be done under proper safety and supervision.
