No. LXI.—CUT AND COME AGAIN
A block of ice would never be divided completely by a loop of wire on which hangs a 5 ℔ weight. For as the wire works its way through, the slit closes up by refreezing, and the weight falls to the ground with the wire, leaving the ice still in a single block.
No. LXIII.—CATCHING THE DICE
It is quite easy to throw the upper of this pair of dice into the air and catch it in the cup, but the other is more elusive. As you throw it upward with sufficient force you will also throw the die that has been already caught out of the cup.
The secret of success lies in dropping the hand and cup rapidly downwards, quitting hold at the same moment of the die, which then falls quietly into the cup held to receive it.
