The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, continue rolling between your hands until it is smooth and round! You can store your plastic ball in a sealed ziploc bag when you are finished playing with it. (The ball tends to flatten out a bit when sitting and does not normally last longer than a couple of days before drying out).
NOTE: The balls will flatten out after sitting for awhile. Erin had the great idea to store them in plastic eggs, but I couldn't find my Easter stuff. We just used small plastic containers and rolled the balls between our palms again to regain their shape.
Even though these aren't as bouncy as a store-bought ball, they're still a lot of fun to make and play with.
