SOAP-BUBBLES, AND
Bubbles and Electricity.
These experiments are on the whole the
most difficult to perform successfully. The
following details should be sufficient to pre-
vent failure. Two rings are formed at the
end of a pair of wires about six inches long
in the straight part. About one inch at the
opposite end from the ring is turned down at
a right angle. These turned-down ends rest
in two holes drilled vertically in a non-
conductor such as ebonite, about two or
three inches apart. Then if all is right the
two rings are horizontal and at the same level,
and they may be moved towards or away from
one another. Separate them a few inches, and
blow a bubble above or below each, making
them nearly the same size. Then bring the
two rings nearer together until the bubbles
just, and only just, rest against one another.
Though they may be hammered together
without joining, they will not remain long
resting in this position, as the convex sur-
faces can readily squeeze out the air. The
