No. LXIV.—WILL THEY FALL?
When the single domino shown in the diagram in front of the double archway, is quite smartly tipped up by the forefinger carefully inserted through the lower arch, the stone which lies flat below another is knocked clean out, while none of the other stones fall, another practical illustration of vis inertiæ.
For this very curious trick, club dominoes, thick and large, should be used. Some patience and experience is needed, but success at last is certain.
No. LXV.—A TRANSPOSITION
You will be able to place the shaded coin between the other two in a straight line without touching one of these, and without moving the other, if you place a finger firmly on the king’s head and then move the shaded coin an inch or two to the right, and flick it back against the coin you hold. The other “tail” coin will then spring away far enough to allow the space that is required.
