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.'"
The new development is that the dye used in the bubbles does 2 things: 1) it actually covers the whole bubble uniformly, rather than sliding to the bottom of the bubble like most colorings do 2) it loses its color if you rub it or if you just wait about a half hour. And when I say lose, I mean goes away completely, not just fades. Very neat chemistry behind it all, actually.
Geek used to be a four letter word. Now it's a six-figure one.
