In addition, the professor will explain a method that enables you to see right through the walls of a house! Count the Clips Remove the contents of a small box of paper clips. Place exactly 20 clips in the box and set the rest of them aside. Select a number fewer than ten. Take that number of clips out of the box and put them in your pocket. Count the number of clips remaining in the box. Add the two digits of the count and remove that number of paper clips from the box. Put them in your pocket.

This tells you how to count to a word in the selected line. What word do you reach? Odd or Even? Put ten cards face down on the table, spread apart in any pattern you like. Now turn over cards as follows: Reverse any single card, then reverse any pair of cards, then any three cards, and so on until you reverse all ten cards. Count the number of face-up cards. Is it odd or even? A Row of Nine From a deck, remove nine cards with values of ace (one) through nine. Arrange them in a row, face down and in counting order, starting with the ace on the left.

Move the dime either down or to the right to the nearest white square. On what square is the dime now resting? What’s the Word? Crease a sheet of paper as shown below and letter the eight cells from A to H. Fold the sheet into a packet eight leaves deep by folding it any way you like along the creases. After you do this, some cells in the packet will face one way, other cells will face the opposite way. Because you made the folds at random, there seems to be no way to know which cells face which way.
