Oh sorry. They're tiny little I guess "beads" and when you put them into water, they grow to be little water filled beads that are very pretty, but they are used for planting. Say someone plants a flower seed, if they put a few orbeez in the soil with the seed, it helps water the seed because eventually the water seeps out of the orbee and helps the flower grow. It has no chemicals. At least that's what's advertised. And they're pretty if you just want to fill a vase with a colored pattern and decorate your house. Personally, I think they're cool! And they grow in a few hours. If you watch them right when you put them in, you could actually see them expanding!
