D. and F. bought one beverage box with 32 bottles for the weekend party, but one of
their four children changed the content of one of the bottles that cannot be
detected easily! To punish the children, they decided to permute the bottles
and ask the children to find it again by tasting them until 11 days later! Unfortunately if
one drinks from THAT bottle, he/she will be sick 10 days later for a week, but the
children like to participate in the party! What is the best strategy
for the children?
