    Soap Made From People

    In 1939, superstitious mother of four Leonarda Cianciulli was convinced by a fortune-teller that her children were in danger and that she must conduct a human sacrifice in order to make them safe again. She then took the lives of four women and disposed of the remains by boiling them in caustic soda.

    Also known as sodium hydroxide, caustic soda is incredibly effective at digesting grease and fat, and by boiling them in it - along with a little cologne - Cianciulli was able to turn her targets into fragrant soap, which she then gifted to friends and neighbors.

    Fleas That Make Your Feet Fall Off

    Tunga penetrans, colloquially known as the chigoe flea, typically attaches itself to the feet of human hosts. They latch onto the skin, conceal their heads in the flesh, and proceed to lay hundreds of eggs. If left untreated, the fleas can cause severe damage, including gangrene, tuberculosis, and necrosis of the flesh.

    Wear some thick shoes if you go hiking in South America or Africa, the places these fleas are the most common.

    Snail Parasites Have Infected People Worldwide

    Certain types of freshwater snails carry parasites that can come off in the water and infect humans who make contact with that water. These parasites, worms from the genus Schistosoma, cause a disease called schistosomiasis by laying eggs that cause inflammation, scarring, and other damage as they travel through the body.

    The afflicted have been known to develop symptoms including anemia, malnutrition, and learning difficulties. The disease can damage the liver, intestines, lungs, and bladder, and it can even cause seizures, paralysis, or spinal cord inflammation.

    Countless Pets Were Put Down As An Unnecessary Precaution

    The British pet massacre occurred in the early years of WWII, when British authorities advised citizens to re-home or euthanize their pets in anticipation of a food shortage due to the conflict. This was thought to be a more humane option when compared with letting them starve or be injured during the fighting, and over 750,000 pets were put down between 1939 and 1940. 

    Tragically, however, it seemed to be unnecessary in the end. Those who did not put down their pets managed their rations just fine, while those who did reported deeply regretting it. Moreover, most pets that survived the initial culling also survived the rest of the conflict, and one home that opened its doors as a shelter for pets that would otherwise be put to sleep managed to care for 145,000 dogs over the course of the war.

    Monkey Madness In Florida

    Sometime in the late 1930s, a number of rhesus macaque monkeys from Asia were set loose in Florida's Silver Springs park, where they proliferated until they numbered in the hundreds. The population today stands at about 300.

    Unfortunately, the Silver Springs monkey colony is infected with the Herpes B virus, which does not affect them negatively but is capable of jumping to humans and causing encephalitis and brain swelling. Of course, this hasn't stopped people from visiting the park in droves to catch a glimpse of the invasive species. So be careful if you go to Florida - for many reasons.

    It's The Human Museum

    Back in the 1800s, the Paris Morgue had public viewing rooms where cadavers were spread out on slanted tables behind glass so visitors could view them.

    The intent of the viewing rooms was to use the public to help identify John and Jane Does. However, the rooms instead became a morbid spectacle and source of entertainment, to the point where British tour guides would list the morgue as a tourist location.
