SOAP-BUBBLES, AND

with a ring on the end. I shall now blow
another air-bubble on this inner ring. The
fnext bubble that I shall blow is
one containing gas, and this is in-
side the other two, and when let
go it rests against the top of the
second bubble. I next make the
second bubble a little lighter by
blowing a little gas into it, and
then make the outer one larger
with air. I can now peel off the
inner ring and take it away, leav-
ing the two inner bubbles free,
inside the outer one (Fig. 63).
And now the multiple reflections
of the brilliant colours of the dif-
>ferent bubbles from one to the
other, set off by the beautiful
forms which the bubbles them-
Fig 62 selves assume, give to the whole a
degree of symmetry and splendour
which you may go far to see equalled in any
other way. I have only to blow a fourth
bubble in real contact with the outer bubble
and the ring, to enable it to peel off and float
away with the other two inside.
