So, we all knew about Mentos and Coke (thanks, Jamie and Adam), but I didn't know that Alka-Seltzer could, in fact, kill a bird or that apple seeds have cyanide! See for yourself!
As we get older, it’s easier to logically dismiss some of the outlandish claims we heard as kids—never really needing to investigate if there’s any truth behind them. But some of these assertions—like whether eating too many carrots will turn you orange or if rice really does harm birds when ingested—tend to keep us guessing far into adulthood. To satisfy our curiosity (and yours) we’ve done research that debunks or confirms common food-related fables.
