According to some reports, toy designer Tim Kehoe spent 15 years and $3 million US to bring his vision of colored soap bubbles to market. Making a colored bubble is apparently hard enough, but the real challenge is making them non-staining. That’s right: By virtue of some very fancy dye chemistry, Zubbles are only colored as bubbles. Once they pop the color disappears. After years of hype, they can finally (and only) be purchased here.
