I bought these for my grandson just to give him an awesome experience for bath time !! Its not something we ever did before, so I just want to gibe my sweet grandbaby a fun, fun, fun time !! The beads are ultra small when you get them, but as they sit they swell up to about the size of a marble. He had fun picking them up and throwing the at the tub wall where they would bounce back at him !! Then I would grab handfuls and drop them on him in which he just had this sincere belly laugh !! I also did use the beads in vases for some fresh cut flowers which made my vase even more beautiful !! They are awesome and fun !!
