Thames and Kosmos – Erupt your own volcano again and again! Press down on the “lava lever” a few times and WOW! The crater pops up and the slime lava flows down its sides. The volcano works with three types of eruptions: heat-activated color-changing slime “lava”, soft foam “lava-rock” balls, and the classic vinegar-and-baking-soda reaction with ingredients from your kitchen cupboard. Customize your volcano with fun stickers of trees, plants, dinosaurs, and more.

Learn about how real volcanoes occur and how the super-cool mechanism inside this toy volcano models the pressure buildup of magma underneath a volcano. The lip around the base catches the lava allowing for easier cleanup, so you can get to your next eruption faster.

A fun, 8-page, full-color experiment manual guides you through using your volcano and provides fun, educational content about volcanoes. Scan the QR code to access exclusive audio content from Wow in the Worlds Guy Raz and Mindy Thomas as they explain the science behind each eruption, reveal fun facts about volcanoes, and even share volcano sounds!

Bonus: The kit includes a durable beaker, a classic scientific tool to aid in future STEM adventures.
