Fun this explosive should carry a health warning. A kit to rock your world. Volcanoes are one of the mightiest forces on our planet. They wiped out the dinosaurs. They cause earthquakes and tsunamis. They can block out the sun. And they also make rather beautiful rocks. Blow your mind and start an instant rock collection with this very special kit. Half of it is a book packed with dramatic facts and photos. The other half is a collector’s display box with nine chunky volcanic rock samples. Incredible history that you can hold in your hand. Want to finish the collection? Get hunting for more rocks!
