Click near the top to start. You can also click and drag up and down. _____________ How I did it: I made the animation using blender from blender.org it has a fluid simulator, so I made some text, converted it to a mesh object, set it as a fluid, then put it in the fluid 'domain' (a box around the objects where the fluid can be.) I did the same with the "DRY" text, but I called it a collision object, so water wont go through it. It can be challengeing to do this. see http://www.totallyblended.com/Tutorials.html Please ask question if you have more questions or would like help.
