Here are the Circuit Playground plushies, we have a lot of things planned with the cute components, from teaching “props” to special projects to puppet versions for our upcoming kid’s show. Most of all we know it’s hard to figure exactly what will spark a young mind on to the journey towards science, technology, engineering, art, math and more – we wish we had these when were young 🙂
