There are lots of fun things to do with pool noodles. I think noodle-sword fights are my kids favorite. I have seen them cut up and used as blocks, stringing them on yarn, stamp painting with them, cut in half to create marble runs with and many others. Just search "pool noodle" on Pinterest and you will have loads of ideas at your fingertips. What I like, is you can find them for less than 1.00 right now! So I bought some, we had a few battles with them, then I cut them into smaller round circles. Then, I set them out with the golf tees and let the kids create.
Of course, T made a robot!
Great for fine motor development, creativity, problem solving and sensory.
