How do you force quit an application in iOS 7? In iOS 6 and below I could double tap the home button, tap and hold an app, and  click the red - to close an application(s).

In iOS 7 this does not work. How can I restart an app that's exploding without resetting the entire OS?
In iOS 7:


Double tap the home button
Scroll to the app you want to force quit 
Flick up on the app's window.
