My daughter loves it
She is 10 years old.  These have kept her occupied for 30 days and counting.  She washes her hands before handling. She changes the water daily to make sure her magic balls do not get moldy.  She likes to keep them in a bowl of water and checks on them after school.  They are like pets but without the feeding and the pooping . It is teaching her responsibility without killing off some poor pet.  They can crack though.  She saves those pieces as well.  Maybe one day, I will get her a cat.  Maybe not.
