What does Odysseus do that almost ruins his clever escape plan?

He didn't tell them what was inside the bag that Aeolus gave him. Odysseus was given a bag full of winds and was told to not open it right away. When he does open it however, the winds will take him straight to Ithaca. He didn't tell his men this. he only told them not to open it. CuriOSity killed them and they just had to open it. When they opened it, the winds caused a windstorm and made them go in the wrong direction.
