If this doesn't capture imaginations, nothing will! Who would have thought there was a certain something lurking inside this active volcano? To operate Seedling's The Dinosaur Who Lived Inside the Volcano, simply fill the container with water. The liquid will begin to foam as the volcano erupts. After the show is over, drain the water out of the jar and fill it with fresh water; then watch as the dinosaur magically appears from within the inferno! Once he's free, again empty the water and replace it with fresh water; and then watch in wonder as your dinosaur gets larger-and-larger... 72 hours later your prehistoric creature will be fully grown. Fascinating! Container height - 9cm. Age guide: from 5-12 years.
