Turn the time off for return Turn for return And say hey! Welcome to today Bye! Bye! Past And will go ahead of time Ahead of time by breaking time machine Match of time Much of mine What would you do if you go back in time? ___ Time Turner is not exactly like a time machine. You can't travel in the future only in the past. It is a magical device which has an hourglass on a necklace. The number of times one turned the hourglass corresponded to the number of hours one travelled back in time. So you can't go way back and it's exhausting. And you can only stay in the past for five hours at a time, without the possibility of serious harm to the traveller or to time itself.
