Imagine a huge colorful bubble, 1 yard in diameter, long-lasting, strong, and bouncy. Imagine fanning your hands around it, making air waves next to it and watching how the wiggling bubble slowly moves from one room of your house to another controlled by your hands circling around it. Would that be a bubble that kids and adults love to play and experiment with? Absolutely! Patented, secret solution formula for durable, bouncy bubbles, non-toxic and stain free, made in Russia. With a skill it allows blowing bubbles as big as 1 yd in diameter. Even small lungs of a 5 years old can blow a biggest bubble ever thanks to the patented bubble-blowing pipe. Only 1/5 of the air that fills this gigantic bubble comes out of the lungs, the rest of it is injected into the bubble by the special bubble-blowing pipe. The kit includes the pipe, matching cup, Wobble Bubble solution, and instructions. Refills are available. No batteries required!
