My grandkids love these rings. I showed them how to hold their arms up and have the hoops run down them, then gently put their arms slowly down and have the hoops run the other way to see them roll again. Then we got a broomstick and rolled the hoops up and down the broomstick so they could see them twirl. These are really pretty. I recommend having an adult play with the kids with these because the children are inquisitive and want to know how they work so they want to bend them and that will damage the rings so they don't twirl. This is a really neat activity for homeschool to teach the kids science.
