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 (1) heat-activated color-changing slime "lava". (2) Soft foam "lava-rock" balls and (3) 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. Ages 4+. 3 Experiments.
