Cannibal Cologne - a fragrance that's anomalous properties only occur on human males and females from 23 to 38 years of age. To the person that it is applied to, it has no odor or affect. When applied, the substance deters non-sentient predatory animals. However, it also stimulates hunger and heightened predatory behavior from others, directed toward the subject. The more of the substance that is applied, the greater the duration and its effects on others. Also, this cognito affect attracts other organic, sentient beings along with humans.
I was thinking the substance either causes it to target people that have been applied with the substance OR it causes degenerative brain function and predatory behavior in people that come in contact.
Grandma's Crockpot - An 18th century lead crockpot and ladle that can make "near" anything edible and delectable when cooked in it. Dead flesh, scrap metal, sewage water, even SCP-835 can be sound to eat and taste like Italian clam chowder.
If either have a slight potential, I'll be happy
