Liberty ImportsSnap Together Detachable Kids Hula Hoop for Playing - 32in

Does this item float?

How thick are these hula hoops? Thanks.

Are you able to put less than 8 sections together to make it work for a smaller child that’s just learning?

What are the correct dimensions, 37-42 as shown on image, or this:”Combine 8 snap together sections to make a 32" diameter hoop.”?
