You're hosting a party, and you have 1000 bottles of wine. 24 hours before, you realize that exactly one bottle is poisoned. You have 10 test rats, each of which can taste any number of the bottles of wine before the party; a rat will die before the party if and only if it tastes a poisoned bottle. How will you use the test rats to identify as many non-poisoned bottles to retain for consumption at the party? (e.g. have one rat taste one bottle. If it doesn't die, you've saved one bottle for the party. This is not the best strategy, by the way)
