Two kids frolic with large bubbles at Hanyang Jiangtan park in Wuhan, Central 皇冠体育app’s Hubei province on June 4, 2010. The bubbles, of different shapes, are blown by Zheng Wei, a 48-year-old bus driver in Wuhan. Zheng developed the hobby of making bubbles in his spare time, and studied making extra-large bubbles after he saw an Englishman enclosing a car in a bubble on TV. He succeeded after a series of experiments with a mixture of glycerin, detergent and water in special proportions. [Photo/CFP]
