Outer Space Explorer Kit
Embark on your adventure into a Martian World with the Outer Space Explorer Set. This amazingly complete set contains 6 different polymers that are so astounding that you will think they are from another planet.
Space Sand is truly the closest thing to sand from mars and will not get wet. Expanding Space Spheres will mimic the expanding universe by growing over 200 times their size when placed in water! Make your own green, gooey Alien slime, solidify water and even mold your own Extraterrestrial friends!
Watch in amazement as Alien Spider Balls open and a multitude of multicolored Space Spheres pour out and expand.
