You have 1000 bottles of wine but one of them is poisoned! you want to find out exactly which bottle is poisoned.

here is my way: first you label all the bottles of wine 1-1000 then you give each prisoner 100 bottles you wait 10 minis apart from each bottle of wine the wait 24 hours then mark the time on the bottle was drunk by the prisoner. on the time that the prisoner dies, you will look at the clock and go back 24 hours and see witch bottle is poisoned, and you will remove the bottle.

You could possibly use science, depending on wht the poison is, you could use chemical reactions in the bottles to find out
