They will remain un-popped on the floor or lawn. For the best results use your hands to wave the bubbles in the air for a moment. The more seconds they float in the air, the lighter and more durable they become. Bubbles dry in the air, and land on the ground intact, waiting to be attacked by cats and dogs alike. Pets really love chasing and bursting these bubbles! Economical and fantastic fun. Nontoxic, of course!
