Zubbles is a commercial name for colored soap bubbles. Zubbles claim to fame is that they are the first colored soap bubbles that do not leave stains. Instead they fade away with exposure to air, pressure, and water. ''Popular Science'' named Zubbles the "Innovation of the Year" for 2005. ''Reader's Digest'' agreed, saying they were one of the "Best Innovations" of the year in 2006. ==Development== Zubbles were invented by Tim Kehoe, a toy creator from St. Paul, Minnesota.〔(''Popular Science'' ) feature, December 2005〕 After an unexplained breakthrough in his kitchen, he was able to produce blue bubbles, that, unsuitably for a toy, stained clothing. After an eight-year-long delay in developing the idea further, he recommenced his investigations after forming a new toy company. In the process of trying to rediscover the recipe, he changed the formula, making the coloring water-soluble. However, having to wash off the color from the bubbles rendered them unsuited to a mass-market toy. Kehoe hired the dye chemist Ram Sabnis, who arrived at a formula where the color would disappear on its own, with sufficient exposure to air, and without washing or staining. The company entered into a global license agreement with Spin Master Ltd. for Zubbles Colored Bubbles in December 2005. Despite announcements of expected release dates, Spin Master dropped plans for commercial production due to complexities in the manufacturing process. In 2008, the company reached a licensing agreement with a new toy company called Jamm Company. Zubbles commenced commercial sales in June 2009. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zubbles」の詳細全文を読む スポンサード リンク
