Scientists pat themselves on the back today for their latest toy: An umbrella that predicts when it's going to rain. But sadly for the Inspector Gadgets out there lusting after this gizmo, they've forgotten an important point: The reason you need to know if it's going to rain is so you can pack your umbrella, or not. If you're already lugging your umbrella everywhere, because it tells you when it needs to be opened... well, then you've got the classic Mean Girls situation that's referenced above. A better suggestion: Make us a pair of shoes that tell us when it's going to rain. And when it does, have the shoes grow a protective coating for the leather. And also: Make a cuter umbrella.
