There are 1000 barrels of wine, of which 1 barrels are poisonous. How many mice do I need at least?

There are 1000 barrels of wine, of which 1 barrels are poisonous. Once eaten, the toxicity can occur after 2 hours of death. Now use the mouse to do the experiment, give you 3 hours to find that bucket of poisoned wine, ask at least how many mice need. (Hint: wine can be mixed)

The title, the mice after a week after a reaction, asked to find 1000 barrels a week after a bucket of wine, the minimum number of mice needed.

One:
The answer is: 10, and Binary, which is a topic of C + +. (Microsoft has been out of this problem)

Two:
Because 2^10 = 1024 the answer is 10.
Specifically you will be the drug from 0000000000-11111001111 number then let each mouse drink a bit of all the water on the 1, and then through the comparison will be able to know

Three:
10 mice were ordered in order, each barrel of wine converted to binary by number, to the corresponding position of 1 of the mice drink. The last mouse to die is a few, and then into a binary system, and then turn into a decimal is the first few barrels of wine
