filled in with wax, which will make the board sound solid when
tapped.

In presenting the trick, the performer gives the hand and board
with wires and switch for examination, keeping the plug concealed
in his right hand. When receiving the board back, the plug is
secretly pushed into the switch, which is held in the right hand.
The hand is then placed on the board over the magnet. When the
performer wishes the hand to move he pushes the plug in, which
turns on the current and causes the magnet to attract the iron in
the wrist, and will, therefore, make the hand rap. The switch can
be made similar to an ordinary push button so the rapping may be
easily controlled without detection by the audience.




** Making Skis and Toboggans [3]

During the winter months everyone is thinking of skating, coasting
or ski running and jumping. Those too timid to run down a hill
standing upright on skis must take their pleasure in coasting or
skating.

The ordinary ski can be made into a coasting ski-toboggan by
joining two pairs together with bars without injury to their use
for running and jumping. The ordinary factory-made skis cost from
$2.50 per pair up, but any boy can make an excellent pair far 50
cents.
