Liquify is perhaps one of the most fun tools in Photoshop. By using the Bloat and Pucker tools inside the Liquify interface, you can expand and shrink parts of your image until it becomes downright scary (see Figure 9.7). Liquify really gives you an opportunity to push pixels around. You can smear them, twirl them, and expand or shrink them, and you can also save your liquefied area as a mesh for use on other images.
Figure 9.7. In the Liquify interface, you can stretch an image in any direction by using tools such as Bloat and Turbulence. Apply a mask to the image so you aren't liquefying everything. Save your mesh so you can liquify other images exactly the same way.
