Idea 1
Marinara sauce brand that when ingested it give the eater intense heartburn until the consumer's stomach acid is so viscous and hot that it burns through the stomach (kinda turns stomach acid into Hydrochloric acid i guess)

Idea 2
Eye drops that cure blindness (Needs some kind of balance, like a consequence or a bad side)

Idea 3
Magnet that attracts organic matter and grows in power (Needs some reason why the magnet is getting stronger)
