Do You Like Money?
I think we can all agree that the best part of a root beer float occurs when the ice cream melts and mixes with the root beer. When they're separate, they are just ice cream and root beer. But when they mix, you get a magical tasting concoction that doesn't occur elsewhere in nature.
I'm telling you - if someone were able to figure out a way to bottle the ice cream/root beer mix and sell it, I'd buy it by the case. It would be a lot easier than having to find an ice cream stand on the run, then waiting for the chemical transformation to take place. It would be a license to print money.
