- I bought two of these kits for my five year olds birthday craft party. The kids loved picking the colours but my husband did have to pour the crystals in for them, as they were spilling the crystals when they were trying to do it on their own. Also, our balls were not completely dry when the box said they would be, so the kids took them home with the advice that they would be better off waiting till the next day to try bouncing them. I did not ask the other parents how well their balls bounced, but the two balls my children made were not very bouncy. They roll nice but only bounce once about three inches high. However, they loved doing this activity and are very proud of their homemade balls!
