ERUPT YOUR OWN VOLCANO AGAIN & AGAIN (3 TYPES OF ERUPTIONS!) - This fun new twist on a classic science experiment works with three different types of eruptions (a color-changing slime eruption, a soft rubber balls eruption, and the tried-and-true vinegar-and-baking-soda eruption) for maximum replayability! (Slime and rubber balls included; baking soda and vinegar sold separately) LEVELED-UP PLAY & CUSTOMIZATION - No two real-life volcanoes are the same, so use the included stickers of dinosaurs, plants, and wacky shapes to personalize your volcano! LEARN HOW REAL VOLCANOES OCCUR - The 8-page, illustrated “Wow-To Guide” walks kids (and their grown-ups!) through tangible, easy-to-understand demonstrations of how a real volcano works. Plus, the model comes equipped with a lip around the base that catches the “lava,” allowing for easier, faster clean-up. It’s the perfect STEM gift for the entire family! BONUS SCIENCE TOOL - This kit comes with a reusable measuring beaker to use during your volcano experiments and to add to your permanent STEM tool collection. EXCLUSIVE AUDIO CONTENT - The #1 family science podcast “Wow in the World” hosts Guy Raz & Mindy Thomas bring you & your family on a bonkerballs journey through the science behind volcanoes! Audio “Wow Facts” await you, accessible only within the pages of the “Wow-To Guide!”
