So it doesn't cure cancer... Neither did cars, but they certainly changed the world. 
Cars allow us to conduct our day to day activities much faster than without.
Coloured bubbles are.... umm.. coloured bubbles *giggle* *giggle* *giggle*

Nice comparison.
----- Failed at being funny again.
I thought you said you read the article.

More important than the bubbles is the dye.
Is it going to be as significant as a car? Probably not.
Is it going to cure cancer? Probably not.
Is it really cool? Yep.
Are there a lot of cool things that could be done with such a thing? Yep.
Yeah... With that car comparison, I meant that colored bubbles were going to change the world JUST like cars did. Yep... That is what I meant.

Just the very fact that the colored bubbles were invented has now changed the world. 12 years ago we had NO colored bubbles. Now we will not only have them, but they will even be non-staining. That is certainly a change.
Since when did the definition of change mean that it had to be about curing cancer (though fun is certainly one big factor in recovery)?

Hell... Since when did change even mean that it had to be something grand or even good?
