When the solution is ready it will feel slightly thick and slimy. Thin your paints with water using about one part paint to three parts water. Glass jars or paper cups work well for thinning paint. You can also create new colors by mixing the primary colors. Paint should be about the consistency of milk and well mixed with the water.
Popsicle sticks work well for mixing.
Applying The Paint Using the squeeze bottles, gently apply the paint to the surface of the solution. Hold the bottle close to the surface and apply one drop at a time. The drops will spread on the surface of the solution leaving a thin layer of paint. Some paint will fall through the solution to the bottom of your pan. This is normal and is not a problem because you will work only on the surface.
