A thin-layer bubble blower includes a thin-layer container of thickness within
2-6 mm, the thin-layer container defining a flat liquid chamber for holding
a bubble solution and an opening in communication with the flat liquid chamber,
and a bubble-blowing bar for blowing the bubble solution into bubbles, the bubble-blowing
bar having a rubber stopper, which seals the opening of the thin-layer container
after insertion of the bubble-blowing bar into the flat liquid chamber.
