Measure glue into a bowl. Add a few drops of food coloring. Once it is the desired color add a few more drops. The shaving cream will make the color lighter. Mix in baking soda then shaving cream, Stir in contact lens solution and mix. The mixture will start to come together. Remove mixture from the bowl and knead with hands. It will be sticky.
Notes
The more it is played with the less sticky it becomes.
