“As some of you have not had the opportunity of personally examining the tube I should like to prove to you in the first place that it is really what it appears to be, a simple cardboard cylinder, open from end to end, and as free from deception as I am myself.
“Proof 1.” (Wand dropped through tube on to table.)
“Proof 2.” (Tube held in front of candle showing flame through it.“)
“Proof 3.” (Tube dropped over candle as in Fig. 30, or spun on wand, held horizontally as in Fig. 31; the halfhoop in each case being made to lie against the side of the tube.)

“I have here a little ball, of such a size that it passes easily through the tube.”[17] The ball is allowed to fall through, from the one hand to the other.
“Now I will place the tube upright on the table and drop the ball in once more. Where is it now? On the table, you say. Quite right: here it is.” (Lift tube, closing it, and placing it on end beside ball.) “But now I take a few handfuls of air and press them well down into the tube” (makes believe to do so), “and I drop the ball in again. This time you see it does not fall through. As a matter of fact it has stopped halfway, resting on the compressed air in the tube.” (Lift tube, showing that the ball has not passed through. After replacing the tube switch the wire loop to the horizontal position, allowing the ball to drop inside the tube.) “I think there can be no doubt that this is the way Mr. Home, the medium, managed to float about with his head in the air and his feet on the mantelpiece. All that was needed was a few pints of compressed air in his tail-pockets. It’s quite simple, when you know how it’s done.
