Difficult General Knowledge Questions and Answersの基本情報から最新動向までを徹底的にカバーしました。

Science is full of “no way” facts. Try this: What is the only metal that is liquid at room temperature? Mercury? Nope, that’s a common mistake. The correct answer is bromine. It’s a non-metal element that drips like water. Freaky.

Or this one: How long does it take for a human body to digest a piece of gum? Seven years? False. That’s a complete myth. Your body digests it in about the same time as a candy bar. The gum just passes through. Don’t believe the old wives’ tale.

Here’s a mind-bender: What is the hardest natural substance on Earth? You’re shouting “Diamond!”. Good guess. But actually, lonsdaleite (a rare form of diamond found in meteorites) is tougher. It’s 58% harder than a regular diamond. Space rocks win again.
