A nozzle attachment connected to the end of a garden hose for emitting a big, soft bubble of water suitable for gently and copiously watering anything in the backyard vegetable and flower gardens, even small lawns. The attachment includes a control valve operable to reduce the bubble size to accommodate the watering of potted plants like a small spouted watering can; or the control valve can be opened wide to produce large drops like rain falling gently of its own weight with a capacity of more than four gallons per minute, and unlike a sprinkling or watering can, it never runs dry.
