Mad Scientist Invents Colored Bubbles
Anonymous Custard writes "Popular Science has a fascinating article up about toy inventor Tim Kehoe's quest to create colored bubbles. 'Chemical burns, ruined clothes, 11 years, half a million dollars--it's not easy to improve the world's most popular toy. ... It turns out that coloring a bubble is an exceptionally difficult bit of chemistry.'"
He's a happy, idea-patented RICH inventor. ;)
That being said, this is EXCELLENT. Imagine possibilities like clothing that changes color depending on the soap you wash it with.
