Real mystery goo.

I see a merchandising opportunity here. http://www.amazon.com/Cleaner-Laptops-Phones-Keyboards-Office/dp/B00D6Y7SPM

It comes in green and other colors. Have the manufacturer put it in KSP Mystery Goo packaging...

Back in the 40s, while looking for a substitute for natural rubber, silly putty was invented.

Later, there was Flubber, then Green Slime from the Ghostbuster's movie.

You could also manufacture that glow-in-the-dark slime that is used in freshmen chemistry courses, and call that mystery goo.

Much less legal hassle to just have some other company alter the packaging of a product they're already manufacturing than to cook up some goop to sell. Squad is a software company, not a manufacturer of products.

BTW, those goops really do clean keyboards, or at least soften the gunge to where it'll wipe off.

The goo is watching you silently.

Ok, I need that. For cleaning my dismally-neglected keyboard.
