From the makers of Gelli Baff comes Slime Baff! Slime Baff is a powder that turns bath water into gooey slime. Sprinkle the powder over the bath water and watch as the water magically turns into gooey slime. When the fun is done simply turn the taps back on to dilute the slime. Gelli Slime gives children a fun bath time, does not block drains and is kind on skin.
