Then brush the retouch tool (smudge tool) in an upward stroke. Be very random and on the puddle just push little bits.
Repeat this procedure on each of the four pics that you duplicated, saving each one either as a jpeg or if you want it to be transparent then as a gif......1,2,3 &4.
Now that you have your four images saved go to animation shop and click on animation wizard.
Use these settings
Click on next, this is the next screen you will see.
Click next and use these settings
Click next and use the settings below
Click next, and click on add image. Navigate to where you saved your 1,2,3 & 4 frames. ( I use the desktop and then delete them afterwards, they are easy to find there). Hold down the Ctrl key and select all four. It doesn't matter in what order they come up as they are random.
Click next and you should have your four frame animation
Click on the view animation and watch it come to life.
