In a few hours they have grown to a giant size! These little water gel balls are so cool! I love all the different colors and how they expand so quickly. One thing I have to add is that the color bleeds a bit into the water so I wouldn't do it in a container that you really use a lot, I think the best way is to just grow them in plastic bags . Also, I didn't know they could shrink to a smaller size too! While I doubt they will actually fit the size they originally came in, I think it will be pretty close! Pretty fun!
