Get ready to cringe.

A new PSA from EngenderHealth’s WTFP?! (Where’s The Family Planning) Campaign takes viewers on a tour through history and the myriad ways women have tried to prevent unwanted pregnancy.

Many of the methods, outlined in the video above, are unsavory at best and dangerous at worst. In ancient Egypt, women used “crocodile dung mixed with honey” for spermicide. In ancient Greece, women drank lead-riddled “blacksmith water,” which is toxic. And in the U.S. during the 1960s, women would put fizzing cola in their vagina after sex as a bizarre — and misguided — way to prevent pregnancy. (The birth control pill was introduced in the U.S. in 1960, but as TIME noted in its 50th anniversary story about the pill, “women usually had to be married to get it.”)
