“What I am going to show you now is not a trick, or, if you can call it a trick, it is one that works itself, for you will see for yourselves that I have really nothing to do with it. It is just an illustration of the force of bad example.
“No doubt you have all heard of a young gentleman called Fidgety Phil. There is a little poem about him. It says:
‘Fidgety Phil
Couldn’t keep still,
Made his mother and father ill.’
“There are a lot more verses but I am sorry to say I don’t know them. However, these few lines are enough to show you what sort of a boy Fidgety Phil was. He was the kind of boy that wherever he is, he wants to be somewhere else. When he was standing up he wanted to sit down, and when he was sitting down he wriggled about on his chair till he was allowed to stand up again.
“These little blocks are all that are left of a box of bricks which are said to have belonged to Fidgety Phil and they show what even a box of bricks may come to if a bad example is constantly set before them. These three little bricks have got to be just as fidgety as Phil was himself. Anyhow, that is the only way in which I can account for their queer behaviour.
“Please have a good look at them, and see if you can discover anything peculiar about them. I can’t, myself.” (The blocks are handed for examination.) “They seem to me to be just ordinary bits of coloured wood, and this square tube is believed to have been a chimney pot belonging to the same set. I want you to notice particularly that the bricks are just the right size to fit closely in the chimney. They go in quite easily; but when they are once inside they can’t turn round, or turn over, or change places. But the curious thing is that though they can’t they do, as you will see presently.
“I place the chimney-pot here on the table, where you can see all round it, and I drop the three bricks into it one by one. Notice particularly the order in which I put them in. First, the blue. You heard it go down. Next, the white, and now, the red. Don’t forget. Blue at the bottom, white in the middle, and red at the top.
“Now, without my saying or doing anything, they will at once begin to shift about. They can’t keep still for more than a few seconds. When I lift off the chimney pot, you will find that they have changed places.” (It is lifted accordingly, performer holding back the uppermost block within it by gentle pressure on opposite angles of the tube, and exhibiting only the three lower blocks now as in Fig. 34.)
