Here are some streamers I made using party ribbon and straws. I just taped them together and BOOM, a fun, active toy that kids love! Keep in mind, they don't last long as the materials are not that sturdy, but they are cheap and easy to make. Also, you could use popsicle sticks for the handles.
The kids really had a good time with these and loved waving them around as they ran around inside on a rainy day.
