Jello is a fascinating material, um "food" when you are 6 years old. All the more fascinating when it isn't on the menu at home. When the little one visits, I help her make a batch and throw it away immediately when she leaves. I may have found another use for it though.
A friend told me about a "JELLO GARDEN" party. They filled up the tub with different colors and shapes of jello, got naked and jumped into the tub. Naughty fun for adults but a perfect for kids. Only I'm gonna do it outside and hose them off when we're done.
