Glow in the dark putty making kit with slime-filled ghost container. Add the ooze powder to the plastic container and then top up with water. Slowly stir the mixture with a stick until it begins to thicken and turn to jelly. After about five to ten minutes the slime will be ready to pour out and use. After brief exposure to light the slime will glow in the dark. The set also includes a sachet of glowing putty as well as a ghostly container for your slime.
