Tolerating Water with wet Objects

My client hates to get her hands wet and refuses to wash them after using the toilet. The staff had been working on a goal to wash her hands but she won't even place them under the water. Her new goal is to tolerate wet hands by removing the balls from a container that has a small amount of water in it and placing them in the 2nd container. She has always liked insertion tasks so she is willing to do this. We will gradually increase the amount of water so that she has to submerge her hands!! Sometimes you need to be a little tricky.....
