Bubble machine

A method of generating a bubble that encloses a smaller bubble inside, comprising:

• providing a first bubble ring that is positioned inside a second larger bubble ring;
• coupling the bubble rings for movement adjacent an air generator;
• and
• moving the first and second bubble rings together in a lateral manner past the air generator where:
• (i) a first portion of the second bubble ring first passes in front of the air generator;
• (ii) the first bubble ring completely passes in front of the air generator while a second portion of the second bubble ring is also passing in front of the air generator;
• and
• (iii) a third portion of the second bubble ring passes in front of an air generator.

A bubble assembly, comprising:

• a housing;
• an air generator associated with the housing;
• and
• a bubble generator positioned in front of the air generator and comprising:
• a loop defining a periphery;
• a first bubble ring directly attached to a portion of the loop in a manner where part of the first bubble ring extends outside the periphery of the loop;
• and
• a second bubble ring directly attached to a portion of the loop and positioned inside the first bubble ring.
