| THAT 'S NOT MAGIC |
| THINK OF A NUMBER |
| This is an almost magical trick. Ask someone to think of a number,less than 10.Tell him to add 1, double the result,multiply by 5, substract 3, multiply by 5 again, substract 8, double the answer, and add 7.Ask him what the result is.At once you tell him the original number that he thought of. METHOD: His result will be a number ending in 61.If it isn't you tell him he made a mistake , which is an even better trick!knock off these two figures, and you have the answer. As an example, suppose he starts with 7. He obtains successively these numbers: 7+1= 8, 8*2= 16 , 16*5 =80 , 80- 3= 77, 77*5=385 , 385-8= 377, 377*2= 754 , 754+7= 761. You knock off the 61, and you get 7, the number he chose to start with. It always works, even with numbers over 10! But you will need pencil and paper to work the numbers out, unless you are very good at mental arithmetic. |

| HOW OLD ARE YOU ? |
| There are several ways of finding someone's age and the month he was born in . Here is one of these methods: ask someone to think of the number of the month he was born ( January = 1, February = 2 , December = 12..), multiply this by 2 and then add 5 . Multiply this figure by 5, and then add his age. Ask him to tell you the number and silentlysubstract 250. The last two numbers of this figure will be the age of the volunteer and the first or the first two numbers will be the month he was born in. For example : age 12 , born in July (7). 7*2= 14 + 5 = 19 * 50 = 950 + 12 = 962 ; 962-250 = 712 . The last two numbers are 12 ; his age.The first number is the 7th month; he was born in July. |

| You will need: bowl of water, pair of scissors, piece of glass. It is possible to cut glass with ordinary scissors in any shape you wish, provided that while cutting you hold the glass and the scissors as well as your hands completely under water. The water deadens the vibrations which make the glass crack. Yes, under water glass can be cut almost as easily as cardboard. |
