“That is the Man”
Fold a piece of paper into four, and cut a pointer out of it, as shown in [Fig. 30]. Now run a needle through a cork and balance the pointer on its tip, as shown. Place an inverted tumbler over the whole contrivance ([Fig. 30a]).
Fig. 30.—The paper pointer.
Fig. 30a.—Pointer mounted on cork.
By rubbing the outside of the tumbler with a piece of rag, or even a handkerchief, you can make the pointer turn in whatever direction you desire, as it will swing round to whatever portion of the glass you happen to rub.
Announce that you will make it point to Mr. Jones. If you then rub the glass on the side nearest to that gentleman, the paper needle will swing round and point directly to him.
By rubbing the handkerchief rapidly round and round the glass the needle will be made to revolve with considerable speed, to the great delight of the younger members of the party.
