The Magic Trick
A boy was putting on a show called 'Winter Magical Tricks'. Today he only wanted to put on one show.
The audience had to guess how he did it, and if they got it 100% right they could win up to fifty dollars.
The magician gave a volunteer from the audience 5 twenty-cent coins. Each of the coins was identical except for the dates. The magician then walked off the stage while the volunteer put the coins in the cup. Then the volunteer took out a coin, noted the date, and then held it tightly in his hands. When the magician came back on to the stage, he started to ask the volunteer questions. This is how the following questions were answered:
'What is your name?'
'Harry.'
'How old are you?'
'13.'
'What is your favorite food?'
'Chocolate'.
'Do you think you're about to get 50 dollars for deciphering this trick?'
'I don't think so.'
Then the volunteer put the coin back in the cup while the magician was turned the other way. The cup was then given to the magician, who dumped the coins into his hand.
'According to this, the coin you were holding was made in 1892.'
'How did you do that?'
Can you decipher how the magician worked this out?

Hint
It has nothing to do with the questions.Answer
The boy's hands warmed the coin up. Since this was the "Winter Magical Tricks" show, the coins were initially cold. The magician simply noted which coin was the warmest.Hide Hint Show Hint Hide Answer Show Answer
