Stress-reliever: Sounds silly, but you should always keep a can of Play-Doh at your desk if you ever start feeling stress or anxiety. Open it up and start kneading it. Roll it in a ball. Make a flower, anything. It honestly works.
Education Tool: Yes, every parent has seen a ton of videos showing Play-Doh for learning the rainbow, but that only covers a few on the color wheel. What does orange and green create? How do you make Brown? Etc. We blend colors to match as true to the real thing as possible. My daughter, at three years old, knew what colors make up each other. She even understands color theory and how some colors make us feel certain ways. And this all came from the two of us playing with colors.
Creativity-Boost: There are reasons why children play with colorful, fun, moldable toys. They are meant to ignite imagination, as well strengthen sensory and motor skills. Adults should, as well. It can calm and redirect your mindset into a lighter and playful one.
