Lost bet and punishment

Nicole lost a bet with her flatmate Amanda. They decided, that the one who loses will be cuffed to something for a long time, wearing an only diaper! That’s why Nicole is tied up for 23 hours and 30 minutes. A moment ago Amanda had to go to work, but she didn’t want to cancel the last 30 minutes, so before she left, she made a multimedia presentation with a count-down timer and a tip on how Nicole can get herself free at the end of this presentation. Unfortunately by accident Nicole lost her chance to free herself and she will have to wait at least the next 8 hours for Amanda to come back home.
