About 8 cups of wine only one glass of wine poisonous, each person whether poisoning can only test once, at least several people need to identify.

This can only be said to be related to the binary system. A person after drinking a cup of wine has two states, 0 is not poisoned, 1 poisoning.

So you need eight specific codes to label each glass of wine. 000, 001, 010, 011, 100, 101, 110, 111.

So three of them are sufficient.

Similarly, if it is 16 cups of wine only a cup of poison, it takes four people to be sufficient.

If you have 1024 glasses of wine, 10 people are sufficient. (Of course, 1 people drink more than 100 cups.) or lick it with your tongue. ：) ）
