Wait. What will they do to babies?!

  If someone swallows more than one, they can pinch together different parts of the intestine or bowl and cause a perforation, which is a serious medical emergency that if untreated will lead to death. It's dangerous for anyone, but babies and toddlers are most likely to actually swallow them.

    It's the only example I know of where swallowing one thing is totally harmless, but swallowing a second one is really seriously dangerous.
