Colour Changing Handkerchief Idea

Why not have paper handkerchiefs that react with tears and change colour. Each time you wipe your tears away you leave a rainbow on the handkerchief that will cheer you up.

The sum code – A way of transmitting whole encoded sentences easily.

1. First create a code key assigning each letter of the alphabet to a number from 1 to 26
2. Second, arrange the numbers into a coded message, it will look like a very long number
3. Work out the sum that would result in that number.
4. Transmit the sum.
5. The receiver of your message works out the sum, using a computer or, for short messages, an electronic calculator.
6. They then use their copy of the code key to decipher the numbers in the message.
7. Simple Example:H = 1, I = O ; Coded Message: HI; Sum transmitted 5 multiplied by 2.

The Game of RIPPLES

1. Ripples is a board game, for two players, played upon a board with a hundred numbered and gridded, light blue and dark blue squares.
2. Ripples is played sideways, with Black starting on the left side of the board and White starting on the right.
3. Players each have 10 cube shaped pieces called stones. One player has 10 black stones and one player has ten white stones.
4. Players take turns rolling a dice and moving 1 piece per turn the number of squares indicated by the dice roll in any direction.
5. Whenever a player moves their piece onto a number it makes any TWO squares adding up to that number ‘attacked’ squares and if an opponent has two pieces on ‘attacked’ squares those pieces are ‘Out’ and must be removed from the board.
6. For example – If a player places a piece on square 11 and their opponent has a piece on both square 5 and square 6 then, because 5 and 6 add up to eleven, both of those pieces are 'Out'.
7. Furthermore, any square is an ‘attacked’ square if it is half of a number that an opponent’s piece is on. Thus, if a player lands on 12 and their opponent has a piece on number six then that piece is 'Out'.
8. Object of the game: The object of the game is to remove all of your opponents pieces from the board.
