Ezy Magic (Tricks You will Do)


Odd
and
Even
You show 10 similar coins and 3 glasses and challenge
your friends to sort all the coins among the glasses so
there are an odd number of coins in each glass!
Your friends will find this easy to do if you don't spell
out the conditions clearly - all coins and all glasses
must be used.
It is really in how you say it. Put 4 coins in 1 glass and 3
coins in each of the others. Then, put one of the
glasses with 3 coins inside the glass that has 4 coins!
Now the glass which you put 4 coins in, has 7 coins in
it.
So all the glasses have an odd number of coins in
them!
