Enjoy over two hours of continuous bubble making with the Bubble Defender Bubble Machine from CITC. This machine breaks from tradition by employing a nozzle-pipe delivery system instead of a dipping wand. The nozzle-pipe method helps prevent bubbles from colliding and breaking prematurely. A 120-oz tank provides over two hours of continuous use. The tank is enclosed to reduce evaporation. 1200-1400, 1.25-3" bubbles are produced per minute, travel 15-30', and can reach a height of 15'. A protected, built-in control makes it possible to change bubble size and angle. Two bubble jets and two variable-speed fans provide more volume. The Bubble Defender includes a wireless remote, power cord, and instructions.
