Liquify Tool- Photoshop

Today in my Advanced Image Manipulation class which is basically a class all about advanced photoshopping we learned a new tool. This new tool is called the liquify tool and basically, you can make people fatter or skinnyer with it. You can make somebodys eyes huge like in those cat and dog hallmark cards. You can warp something and make it all weird looking. Thats basically what the liquify tool does. Thus, I've been playing around with it in class and I felt like posting some of the pictures here.
The first picture is just one of my friend Mike that I shot a while ago and the second image is a random image of Obama that our teacher gave us.
