About This

• REAL SPACE SCIENCE KIDS CAN HOLD, BUILD AND LAUNCH: Mix stretchy galaxy slime packed with chunky glitter, mold a jelly rocketship from gel powder, sculpt moonrocks, and ignite a fizzing sun reactor with a real acid-base chemical reaction. Every experiment ends with something kids made themselves.
• BUILD A WORKING TELESCOPE AND PAPER ROCKET: Kids assemble a real two-lens telescope from the included components, then build and launch a paper rocketship using a straw.
• 30 EXPERIMENTS SPANNING ASTRONOMY, CHEMISTRY AND GEOLOGY: 15 guided kit activities cover deep space slime, glowing galaxy slime, moon sand, moon phases, crater formation, bouncy ball chemistry, glacier crystal growing, glow window decorations, planet discovery, and more, with a 15-experiment bonus booklet that keeps things going using household materials.
• THE SCIENCE ACTUALLY GETS EXPLAINED: Every activity includes a plain-language explainer and an observation prompt so kids understand what they just did and why it worked, from polymer cross-linking in the bouncy ball to how Earth's atmosphere burns up meteors before they hit the ground.
• COMPLETE KIT WITH ALL SUPPLIES INCLUDED: Comes with slime powders, crystal growing powder, bouncy ball powder, gel powder, glow paint, glitter, food coloring, balloon, moon phase dial, rocketship and bouncy ball molds, mixing bowls, measuring cup, convex lenses, telescope boxes, and more. Everything for all 15 guided experiments is in the box.
• A STEM SCIENCE GIFT KIDS AGES 8 TO 12 WILL ACTUALLY USE: Carries the STEM Seal of Authenticity with illustrated step-by-step instructions and science explainers built into every activity. A strong birthday or holiday science gift for kids who like building, mixing, and figuring out how things work.
