I'm sitting here watching TV with my DD. She is watching some crazy channel with kids cartoons on it. Well a commercial comes on for Gelli Baff. You simply fill the tub with water and pour in Gelli Baff. The water immediately turns to a brightly colored tub full of jelly. Tons of fun for the kids! When their done, simply pour in the deactivator and it tuns to water again. Just what I want is a tub full of jelly.
