Kids will love to learn while getting their slime on with this Space Adventure Series Planetary Goo Moon Edition. The goop comes inside a snap-close round container and a plastic stand with the word MOON. The pearlescent white goo can be pulled, stretched, rolled, and thrown. When not in use, put the goop back inside the container and place it on the stand. Great for classrooms or homeschooling. Comes packaged inside a hanging window box.
