### 100 General Knowledge Facts That Will Make You Sound Smarter

Knowing things — really knowing them — is one of the most reliable ways to make yourself more interesting in any room. Not in an insufferable way. In the way where you casually drop a fact mid-conversation that makes everyone stop and pull out their phones to verify it. And then it checks out, and everyone thinks you're a genius.

These 100 general knowledge facts are organized across seven categories: science, history, nature, space, the human body, technology, and language. Each one is verifiable, genuinely surprising, and built for exactly those moments.

### Science Facts

**1. Hot water can freeze faster than cold water under certain conditions.** This is called the Mpemba effect, named after Tanzanian student Erasto Mpemba, who noticed it while making ice cream in 1963. Scientists still debate the exact mechanism, but the phenomenon has been repeatedly documented.

**2. A bolt of lightning is five times hotter than the surface of the Sun.** The surface of the Sun is about 5,500°C. A lightning bolt reaches approximately 30,000°C — briefly, but measurably.
