Being a scientist is fun, conducting new experiments every day, some of them totally crazy — like counting all the ants on Earth, asking a dolphin to speak on the phone, or watching butterflies in an earthquake.
We at Bright Side know that such experiments can prove incredible facts, so we chose those we considered the best to share with you.
Oxford University is older than the Aztec Empire.
The first students came to Oxford in 1096, while the Aztec city-state of Tenochtitlan was founded in 1325. That means the university is 200 years older.

When we promise something, we make a “pinky promise.” This means the one who breaks the vow must cut off their little finger.
The gesture originally came from Japan. When making a promise, children link their little fingers and say a certain vow, different in every culture.
But in fact, during the Edo period (1603–1868), bandit clans had a ritual of cutting off their right little fingers to prove their loyalty. It was only much later that kids turned this tradition into a game.
