The First Newspaper

This one goes to the Romans! They had “Acta Diurna” (Daily Events) which was a handwritten news report, posted in multiple public places for the public to read. It first appeared in 131 BCE during the Republic. Although initially only the outcomes of trials, the Acta Diurna eventually expanded to public notices and announcements like important births or senatorial decrees.

The First Pizza Joint

Antica Pizzeria Port'Alba, in Naples, Italy, is widely considered the world’s first pizzeria. It was first established in 1738 as a peddler’s stand. In 1830, it became a brick-and-mortar restaurant in the town center. Since its opening day, their ovens have been lined with lava rocks taken from nearby Mount Vesuvius.

Luminol is a chemical that can be used to show trace amounts of blood by creating a light producing chemical reaction when mixed with hemoglobin.

Luminol powder is mixed into a liquid containing hydrogen peroxide and other chemicals. This mixture will then be sprayed over the area that is being examined.

The reaction of the Luminol spray mixing with the iron in blood will then produce a blue glow that can be seen in a dark room.

Other substances that can accidentally have the same reaction with Luminol are: bleach, urine, faeces & horseradish.

Unfortunately Luminol can destroy other crime scene evidence so it is usually used after other options have been explored.
