Only one! Allspice is not a mix of spices. It is a single spice-sourced from the Caribbean tree Pimenta dioica, also known as pimenta, pimento, and Jamaican pepper in various places around the world.

Japan! Fortune cookies are not authentically part of Chinese cuisine, despite their ubiquity in Chinese restaurants in the United States and other Western countries. They originated in Japan and were introduced to the US by the Japanese.In China, they are considered American, and are rare.

Not by blowing on a paper that's for sure! Although a common classroom experiment is often explained this way, Bernoulli's principle applies only within a flow field, and the air above and below the paper are in different flow fields. The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the airflow.

No. People do not use only 10% of their brains. While it is true that a small minority of neurons in the brain are actively firing at any one time, a healthy human will normally use most of their brain over the course of a day, and the inactive neurons are important aswell. The idea that activating 100% of the brain would allow someone to achieve their maximum potential and/or gain various psychic abilities is common in folklore and fiction, but doing so in real life would likely result in a fatal seizure. This misconception was attributed to late 19th century leading thinker William James, who apparently used the expression only metaphorically.

Lmao no. Albert Einstein did not fail mathematics classes in school. Einstein remarked, "I never failed in mathematics.... Before I was fifteen I had mastered differential and integral calculus." Einstein did, however, fail his first entrance exam into the Swiss Federal Polytechnic School (ETH) in 1895, when he was two years younger than his fellow students, but scored exceedingly well in the mathematics and science sections, and then passed on his second attempt. The misconception likely stems from different grading systems in Switzerland and Germany, where a 6 is the best grade in Switzerland, but the worst grade in Germany.
