An Irish-American has invented the world’s first Coloured Bubble. There’s a fascinating article over on Popular Science detailing the entire story. Amazingly enough what began as a concept for a children’s toy will likely effect the entire color industry (is there such an industry). Everything from paint that disappears from every surface except a special paper to toothpaste that makes a kid’s mouth a funny colour until they’ve brushed for the right amount of time. Really cool story.
