Ah? In the Dutch version she drinks it: "Then she drank several big gulps. Anika, who knew that some bottles had written on them "External", was getting anxious. 'But Pippi' she said, 'how do you know that there is nothing toxic?' 'Oh I'll find out tomorrow', Pippi said cheerfully. 'If I'm not dead by then, it's not toxic and any small child can drink it'." Which version are you talking about? The French?
