Impress future geophysicists with a volcano that erupts again and again! Press down on the "lava lever" a few times and - WOW - the crater pops up and slime lava flows down its sides. The volcano works with three types of eruptions: heat-activated colour-changing slime "lava", soft foam "lava-rock" balls, and the classic vinegar-and-baking-soda reaction with kitchen cupboard ingredients. The STEM instruction guide teaches kids how the super-cool mechanism inside this volcano models the pressure buildup of magma underneath a real one. Curiosity, supercharged! Thames & Kosmos teams up with trailblazing podcast company Wondery Kids in a first-of-its-kind collaboration to give children a totally new way to play! The "Wow in the World" line offers high-quality, hands-on physical STEM toys complemented by engaging, exclusive audio content from the ultimate science podcast for the whole family, "Wow in the World"!
Comes with a durable beaker that kids can add to their STEM gear collection for extended play and exploration! Includes a free 3-month subscription to Wondery+ and its expansive catalogue of podcasts.
